Abu Harun narrates: We asked Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him): "Do you remember anything from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) used to recite after giving the salam?" He said: "Yes. He (peace and blessings be upon him) used to recite: 'Glorified is your Lord, the Lord of might, above what they describe. And peace be upon the messengers, and all praise is for Allah, the Lord of all the worlds.'"
Abu Ya'la recorded it, and its narrators are thiqat (trustworthy). (Allamah al-Haythami says:) I say: I have mentioned this chapter here only to draw attention to the adhkar and supplications that will come later, which are recited after the prayer or at other times, if Allah wills (they will come later).
