Answered by Shaykh Abdul-Rahim Reasat
Question
If I recite al-Hamd mistakenly before attaḥiyaiyaat in the last sitting and then do the prostration of forgetfulness. After prostration of forgetfulness if I again mistakenly recite al-Hamd before attaḥiyaiyaat do I need to do the prostration of forgetfulness again or my prayer is valid without it.
Answer
I pray you are well.
If you made another mistake after performing the prostration of forgetfulness you do not need to repeat the prostration. Simply end your prayer. [Shurunbulali, Maraqi al-Falah]
After thinking about this matter, one realizes how profound this ruling is in its implications for Allah Most High. Allah Most High does not demand perfection from us – only He is perfect. Yet, He does not hasten to punish mistakes either. Some He overlooks; others He gives us ways and means to compensate for; and others still, He inspires us to repent from, thereby raising our ranks, because, “Indeed, Allah loves those who repeatedly repent.” [Quran, 2:222]
May Allah grant you the best of both worlds.
