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 bihamdika; Allahumma ighfirli (I testify the Uniqueness of our Lord, and all the praises are for Him: O Allah, forgive me! )
