English Commentary: 1: Regarding the time of acceptance of supplication mentioned in this narration, it is only this particular portion of the hadith that is weak, not the entire hadith in general.
Note: (This chain of narration is among the most well-known weak chains, there are many weak narrators, and their father, Abdullah—Abdullah bin Amr bin Awf al-Muzani—is considered “maqbul” (acceptable) only in cases of corroboration; otherwise, he is a weak narrator.)
