The ruling on supplication after the obligatory prayer, raising the hands, and collective supplication

Question:
The questioner says: Honorable Shaykh, what is the ruling on supplication after the obligatory prayer, and does one raise his hands?

Answer:
Supplication after the obligatory prayer is prescribed and recommended, and it is likely to be answered because it follows an act of worship. However, one does not raise his hands after the obligatory prayer; this has not been reported. It has not been reported that the Messenger (peace and blessings be upon him) raised his hands after the obligatory prayer. This is an innovation; raising the hands after the obligatory prayer is an innovation. As for after a voluntary prayer, there is no harm. Yes.
