Evil Deeds and Their Evil Outcomes
In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Smoking is forbidden due to the evidences found in the Qur’aan and the Sunnah, and based on sound opinion. Allaah [The Mighty and Majestic] said:
[وَلا تَقْتُلُوا أَنْفُسَكُمْ إِنَّ اللَّهَ كَانَ بِكُمْ رَحِيماً – And do not kill yourselves (nor kill one another). Surely, Allah is Most Merciful to you] [Soorah Nisaa: Ayah: 29]
It is well-known that smoking causes harm to the body which may appear sooner or later, and this is an affair agreed upon by the doctors of today after the advancement of medicine. Smoking also disfigures the teeth, the lips etc.
Also, Allaah [the Most High] said: [وَلا تُؤْتُوا السُّفَهَاءَ أَمْوَالَكُمُ الَّتِي جَعَلَ اللَّهُ لَكُمْ قِيَاماً – And give not unto the foolish your property which Allah has made a means of support for you]. Therefore, Allaah clarified the wisdom behind wealth and that He made it a means of support through which the Religious and worldly benefits are established. And it is well known that spending wealth on cigarettes neither supports Religious nor worldly benefits, rather it does the opposite.
And from the evidences in the Sunnah concerning the impermissibility of smoking is that the Prophet [sallal-laahu-alayhi-wasallam] forbade the squandering of wealth, and squandering wealth is when it is spent in other than what is beneficial. It is well known that spending wealth on smoking is a spending in which there is no benefit, rather it is spending in that which is harmful.
As for sound opinion, then sound intellect necessitates that a person does not partake in that which harms him and wastes his wealth, whilst he is a believer and that he will be brought to account. Therefore, sound intellect necessitates that a person does what benefits him and leaves what harms him, and from the perfection of [one’s religion and character] is to leave that which is of no benefit.
The affairs are three: [1] Beneficial things [2] Harmful things [3] Things in which there is neither harm nor benefit. The first affair is sought after, the second affair is blameworthy, and regarding the third affair, a person refrains from it out of seeking perfection in his affairs, but there is no blame on him if he does it.

Abu Hafs [rahimahullaah] said to Abu Uthmaan Al-Naysaabooriy [rahimahullaah]:
When you sit with the people, then be an admonisher of your heart and soul, and do not be deceived by their gathering around you, for they [are only] aware of what they can see apparently, whilst Allaah is all aware of your inner self [i.e. your heart, soul]

Al-Allaamah Abdur-Rahmaan Ibn Yahyah Al-Mu’allimee [rahimahullaah] stated:
The human being does not [initially] hate truth because of considering it to be falsehood; rather he [or she] loves truth by way of his [or her] Fitra [natural inclination] and loves falsehood due to his [her] desires and lusts. The shift towards success or loss defends on what he [or she] gives preference.
Allaah [The Blessed and Exalted] said:
[فَأَمَّا مَن طَغَىٰ]
[وَءَاثَرَ ٱلۡحَيَوٰةَ ٱلدُّنۡيَا]
[فَإِنَّ ٱلۡجَحِيمَ هِىَ ٱلۡمَأۡوَىٰ]
[وَأَمَّا مَنۡ خَافَ مَقَامَ رَبِّهِۦ وَنَهَى ٱلنَّفۡسَ عَنِ ٱلۡهَوَىٰ]
[فَإِنَّ ٱلۡجَنَّةَ هِىَ ٱلۡمَأۡوَىٰ]
Then, for him who Tagha (transgressed) and preferred the life of this world (by following his evil desires and lusts), Verily, his abode will be Hell-fire; But as for him who feared standing before his Lord, and restrained himself from impure evil desires, and lusts. Verily, Paradise will be his abode.” [An-Naazi’aat. Ayah:37-41]

In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Allaah (The Most High) said:
ظَهَرَ ٱلۡفَسَادُ فِى ٱلۡبَرِّ وَٱلۡبَحۡرِ بِمَا كَسَبَتۡ أَيۡدِى ٱلنَّاسِ لِيُذِيقَهُم بَعۡضَ ٱلَّذِى عَمِلُواْ لَعَلَّهُمۡ يَرۡجِعُونَ
‘’Evil (sins and disobedience of Allah, etc.) has appeared on land and sea because of what the hands of men have earned.’’ (Soorah Ruum; Ayah:41]
Imaam Ibnul Qayyim(rahimahullaah) said:
This ayah was revealed regarding the state of affairs of the world- the relationship between it and the events that occur. You see how the occurrence of those evil actions and defects (of the people) affects the harvest, vegetation and the animals in every era, and the manner in which those evil (affairs) necessitates other evils. And whenever the people initiate oppression and wickedness, their Lord (The Blessed and Most High) brings about- from those evils and defects (of theirs)- deficiencies and harm in their nourishments, fruits, atmospheres, bodies, physical natures, outward appearances and manners, as a justification for their deeds, acts of oppression and wickedness.
Indeed, the grains of wheat and other than them used to be bigger than what they are today, just as the blessing in them was greater. Imaam Ahmad (rahimahullaah) narrated with his chain of transmission that a packet was found in one of the treasury departments of Bani Umayyah in which there was a grain nearly the size of a date. This grain was grown and harvested during an era of justice.
The majority of the illnesses and the general evil affairs are remnants of the punishment afflicted upon the people of the previous nations; then there remained from that what remains, as a surprise punishment against those who remain upon the (evil) deeds of those previous nations. This is a just judgement and just decree. And indeed the Prophet (sallal-laahu-alayhi-wasallam) has indicated to this in his statement concerning plagues, that ”it is a remnant of an affliction or punishment that was sent by Allaah to the Children of Israa’eel.’’

Contemplation
Abu Amr Ibnul Alaa [rahimahullaah] said:
We are nothing compared to those who have preceded [i.e. the Salaf] except like a sprout on the long roots of a date palm tree.
موضح أوهام الجمع والتفريق
[1/12-13 ‘ by Khateeb Al-Baghdaadi (rahimahullaah)]
In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Imaam Ibnul Qayyim [rahimahullaah] said:
There is no doubt that the one who is obeyed by the people [finds himself in] three situations: Firstly, he gives them orders and prohibits them [from certain actions] for their own welfare. Secondly, he obligates on them that which they must do in order to obey him. Thirdly, the people with him are of divided two categories: The loyal one who agrees with him and the obstinate one who opposes him, and they have rights he must fulfil. His obligation with regards to giving them orders and restraining them [from evil] is that he commands them with good in order to bring about rectification for them in their personal affairs and forbids them from what is in opposition that.
His Obligations towards the Obedient Ones:
His obligation towards those who obey him is that he enjoins on them that which is easy. He should be generous to those who are submissive and are not hesitant to obey him. He should not burden them with hardship and difficulties, and thus corrupts their affair.
His Obligations towards the Foolish Ones:
His obligation towards the foolish ones – those who act foolishness towards him- is that he turns away from them, neither responding to them in like manner nor taking revenge against them for himself. Indeed, Allaah [The Most High] said to His Prophet [sallal-laahu-alayhi-wasallam]:
خُذِ ٱلۡعَفۡوَ وَأۡمُرۡ بِٱلۡعُرۡفِ وَأَعۡرِضۡ عَنِ ٱلۡجَـٰهِلِينَ
Show forgiveness, enjoin what is good, and turn away from the foolish.
And what is intended [in this ayah] is not that [one] turns away from the one who has no knowledge and not to teach and guide him, rather what is intended is that [one] turns away from the foolishness of the one who behaves foolishly towards him, and he does not respond to him in like manner. This Ayah contains the affair of excellent social relationship with the people – fulfilling their rights and safeguarding oneself from their evil. And had all the people adhered to this ayah, it would have sufficed them and brought them close to one another, for indeed being forgiving [in reality] is to overlook the [bad] manners of the people and being tolerant towards their characters.
