Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates: When the Prophet (peace and blessings be upon him) was performing sa'i in the bottom of the valley, he would supplicate: "O Allah, forgive and have mercy; indeed, You are the Most Mighty, the Most Noble."
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat. Its chain contains Layth bin Abi Sulaym, who is thiqah (trustworthy) but a mudallis (one who conceals defects in the chain).
