O Muslim Ummah! Call yourselves to account, repent to your Lord, ask for His Forgiveness, rush towards obedience to Him and guard yourselves against disobedience to Him….
Imaam Abdul Azeez Bin Baaz (rahimahullaah) stated:
O Muslim Ummah! Call yourselves to account, repent to your Lord, ask for His Forgiveness, rush towards obedience to Him and guard yourselves against disobedience to Him. Co-operate upon righteousness and piety, and do good, truly Allaah loves the good-doers. Be just, truly Allaah loves those who are just. Perform numerous righteous deeds before death approaches.
Be merciful to your weak ones and be charitable to your poor ones. Increase in the Remembrance of Allaah and in seeking His Forgiveness. Enjoin good and forbid evil in order that you may be shown mercy. Take a lesson from the calamities that have afflicted others due to sins and disobedience. Indeed, Allaah accepts the repentance of those who repent and shows Mercy to the good-doers. Allaah (Glorified be He) will give the good end results to the pious ones, as He (Glorified be He) stated:
فَاصْبِرْ ۖ إِنَّ الْعَاقِبَةَ لِلْمُتَّقِينَ
So be patient. Surely, the (good) end is for the Muttaqûn. 11:49
Allaah (The Most High) said:
إِنَّ اللَّهَ مَعَ الَّذِينَ اتَّقَوا وَّالَّذِينَ هُم مُّحْسِنُونَ
Truly, Allâh is with those who fear Him (keep their duty unto Him), and those who are Muhsinûn (good-doers) 16:128
Allah responds to supplication when asked through His Beautiful Names and Lofty Attributes, so we ask Him to show mercy to His Muslim slaves. And that He gives them understanding of their religion and aids them against His enemies and their enemies. And that He sends down suffering on them (i.e. the enemies of Allaah and the Muslim) – a type of suffering that is not averted from a rebellious people. Indeed, Allaah has authority and power over that. And may peace and blessings be upon our Prophet Muhammad, his family, his companions and those who follow them in goodness till the Day of Judgment.
