What is the ruling on supplication at the completion of the Qur'an in prayer?

Question : What is the preferred ruling regarding supplication at the completion of the Qur'an in the night prayer of Ramadan? Is it better for the imam to conclude with supplication or not?

Answer : Scholars have differed on the ruling of supplication at the completion of the Qur'an in prayer. Some hold that it is recommended (mustahabb) based on the generality of the hadith they cited, which states that at the completion of the Qur'an, a supplication is answered. They argued that this is a general statement covering prayer and other contexts, and thus they recommended supplication in prayer just as they recommended it outside of prayer. Other scholars say, "No, this is supplication outside of prayer, so it is not recommended to recite supplication [in prayer]." However, outside of prayer, there is no harm in it. This is the ruling. As for a person who is following an imam, he should follow him and say "Ameen" to his supplication, whether the imam prolongs it or not.
