Narrated Aisha:
“When the “Surat-An-Nasr”, ‘When comes the Help of Allah and the conquest,’ had been revealed
to the Prophet he did not offer any prayer except that he said therein, “Subhanka Rabbana wa bi –
hamdika; Allahumma ighfirli (I testify the Uniqueness of our Lord, and all the praises are for Him: O
Allah, forgive me!”)
