Regarding such additions, Ibn Hajar said:
‘None of the ah?d?th that state the ’Ath?n mentions such phrases like “Ad-Darajatar Rafi‘ah” or “Y? Arhamar R?him?in” at its end, as Ar-R?fi‘? stated in “Al-Muharrar”’. (1)
It is also not of Sunnah to add “Innaka L? Tukhliful M?‘?d” to this Du‘?’. This statement was narrated by Al-Baihaq? in his “As-Sunnan Al-Kubr?”. (2)
This addition is, however, Sh?ththah; it was not narrated in all of the ah?d?th ‘Al? Ibn ‘Ayy?sh narrated, except in the one narrated by Al-Kashmah?n? of the ah?d?th of Sah?h Al-Bukh?r? which differs from all the other narrations of the Sah?h by other narrators. That is why Al-H?fith did not mention it in “Al-Fath” (3) though his way is to collect the additions in had?th narrations. (4)
Other false additions:
* Reciting during the sunset ’Ath?n “All?humma H?th? Iqb?lu Lailika Wa’idb?ru Nah?rik ... ” The Had?th that states this addition is weak. It was narrated by At-Tirmith? and others from Ab? Kath?r, the manumitted slave of ’Umm Salamah.
At-Tirmith? stated that ‘this had?th is Garib, and Ab? Kath?r is an unknown narrator’. An-Nawaw? affirmed the same and said that this had?th was narrated by both Ab? D?w?d and At-Tirmith? with one of the narrators being unknown.
Accordingly, such had?th must not be mentioned in public without stating its weakness. (5)
* Reciting “Sadaqta Wa Bararta” when the Mu’aththin says “As-Sal?tu Khairun Minan Nawm” in the Fajr ’Ath?n.
