Some Ma’m?m?n may recite other Du‘?’s when the Im?m is about to finish his recitation of the F?tihah in order that all Ma’m?m?n say ‘?m?n on his [i.e. the Ma’m?m’s] du‘?’s -as he mistakenly believes. This poor Ma’m?m is not aware that the praying Muslims say ‘?m?n for the F?tihah not for his false du‘?’s!!

Two points are worth mentioning here:

[2/ 40] The first: it is of Sunnah that the Im?m recites the word “‘?m?n” loudly after reciting the F?tihah. This is clearly stated in Ab? Hurairah’s ( - رضي الله عنه -) had?th that says: ‘The prophet ( - صلى الله عليه وسلم -) used to raise his voice with the word ’?m?n after reciting the F?tihah’. (1)

The aforementioned had?th states clearly the legality of raising the voice with Ta’m?n [i.e. saying ’?m?n] by the Im?m, this view is held by Ash-Sh?fi‘?, Ahmad, Ish?q, and many other Im?ms. So did Im?m Al-Bukh?r? who titled a section in his Sah?h with: “The Im?m raises his voice with Ta’m?n” and then stated a group of ’?thar and an authentic had?th to support this view. Some of these are:

(a) It is related that ‘Ibn Az-Zubair and those behind him recited Ta’m?n louldly that the mosque was filled with their sounds’.

(b) N?fi’ said: ‘Ibn ‘Umar ( - رضي الله عنه -) used to recite “?m?n” always and urge other muslims to recite it and related many good ah?d?th about it’.

(c) Abu Hurairah ( - رضي الله عنه -) related that the prophet ( - صلى الله عليه وسلم -) said: ‘When the Im?m says ‘?m?n, repeat the same after him. Whosever his Ta’m?n coincides with that of the Angels, all his past sins will be forgiven’. (2)
