It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that when Surah Nasr was revealed to the Prophet (peace and blessings be upon him), he began to say frequently: " «سُبْحَانَكَ اللّٰهُمَّ وَبِحَمْدِكَ اللّٰهُمَّ اغْفِرْ لِي إِنَّكَ أَنْتَ التَّوَّابُ» " "Glory is to You, O our Lord! And all praise is for You. O Allah! Forgive me, for surely You are the Acceptor of repentance, the Most Merciful."
