Musannaf Ibn Abi Shaybah 37760 — The reward of glorifying and praising

It is narrated from Thabit al-Bunani that he said: One of the Companions of the Messenger of Allah (peace and blessings be upon him) (may Allah be pleased with him) narrated this to me beside this pillar. He said: Whoever says 'Subhan Allahi wa bihamdihi, wa astaghfirullaha wa atubu ilayhi' (Glory be to Allah and praise be to Him, and I seek the forgiveness of Allah and turn to Him in repentance), it is written on a parchment, and then a seal of musk is stamped upon it. It will not be broken until he comes with it on the Day of Resurrection.
