Riyad as-Salihin, 1415

Thauban (May Allah be pleased with him) reported:

Whenever the Messenger of Allah (ﷺ) concluded his prayer, he would beg forgiveness from Allah thrice and then would recite: "Allahumma Antas- Salamu, wa minkas-salamu, tabarakta ya Dhal-Jalali wal-Ikram (O Allah, You are the Grantor of security, and security comes from You. You are Blessing, O You Who have majesty and nobility)!" (Imam) Al-Awza'i, one of the narrators of this Hadith, was asked: "How forgiveness is to be sought?" He answered: "The Messenger of Allah (ﷺ) used to say: 'Astaghfirullah! Astaghfirullah! (I beseech Allah for forgiveness, I beseech Allah for forgiveness)'." [Muslim].

وعن ثوبان رضي الله عنه قال‏:‏ كان رسول الله صلى الله عليه وسلم‏:‏ إذا انصرف من صلاته استغفر ثلاثا ، وقال ‏:‏ ‏

‏ اللهم أنت السلام ومنك السلام تباركت يا ذا الجلال والإكرام “ قيل للأوزاعي ، وهو أحد رواة الحديث ‏:‏ كيف الاستغفار ‏؟‏ قال ‏:‏ يقول ‏:‏ أستغفر الله أستغفر الله ‏

‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏

Guidance from the Hadith: 1) Seeking forgiveness after finishing the prayer suits the purpose of asking Allah to pardon whatever shortcomings, negligence, or deficiency that might have occurred in the prayer. 2) Imploring Allah Almighty through His Name As-Salām (the Perfection) is meant for asking Allah Almighty to make the prayer free of any faults so that it expiates the worshiper’s sins and raises him in rank. 3) The manner of seeking forgiveness upon ending the prayer is for the worshiper to say: “Astaghfirullah, Astaghfirullah, Astaghfirullah.” This is the guidance of the Prophet (may Allah’s peace and blessings be upon him) in this regard. Thus, a Muslim should not be deceived by what people do in some mosques, like making additions to this formula, along with engaging in collective Istighfār, for all this is against the prophetic Sunnah.
