Hadith.1189 - Abu Bakr ibn Abi Samal who said: "I prayed behind Abu Abdullah (as) for Fajr (dawn prayer). When he finished the recitation in the second rak'ah, he raised his voice slightly as if reciting and said: Allahumma ighfir lana wa irhamna wa ‘afina wa ‘u‘fu ‘anna fi ad-dunya wa al-akhirah. Innaka ‘ala kulli shay’in qadeer 'O’ Allah (swt), forgive us, have mercy on us, grant us well-being, and pardon us in this world and the Hereafter. Truly, You have power over all things.'".

Hadith.1190 - Hafs ibn al-Bakhtari narrated from Imam Jafar ibn Muhammad Al-Sadiq (as) who said: "It is appropriate for the Imam to sit until those behind him complete their prayers. The Imam should also recite the tashahhud (testimony of faith) loud enough for those behind him to hear, but they should not make their recitation audible to him—referring to the two testimonies (Shahadatayn). He should also audibly recite 'Peace be upon us and upon the righteous servants of Allah (swt).'"
