Remaining in your place after prayer.
Ibn Battal رحمه الله said:
"Whoever has many sins and wishes for those sins to be removed without any hardship, then he should make the most of the opportunity of remaining in his place after the completion of his prayer, in order for the Angels to increase in their supplications for him and increase in their asking for forgiveness for him."
