In At-Tirmidhi (3474, 3534), Al-Bazzar (4050), An-Nasa’i in A'mal al-Yawm wal Laylah (127), At-Tabarani in Ad-Du'a (706), and others; it is related to recite ten/one-hundred times after Fajr and Maghrib:
La ilaha illallah, wahdahu la sharika lah, la hul mulk, wa la hul hamd, (bi-yadihil khayr), yuhyi wa yumit, wa huwa ala kulli shay-in qadir - "while [your] feet are still folded, [...]".
Is this part of the narration about reciting the dhikr "while your feet should be still folded" weak and what is the issue with it?
There have been discussions about this part concerning its authenticity if this only counts for the people praying behind the Imam, or that even the Imam should delay his sitting for this dhikr after Fajr/Maghrib before he would turn around to the people.
I have received this from Islamqa regarding this issue, but I can not understand Arabic, and it was mentioned that Imam Daraqutni (in “Al-Illal” (6/46, 248-249)) and others have commented this dhikr.
