Musannaf Ibn Abi Shayba 21:407

'Affan narrated to us, Hammad bin Salamah narrated to us, 'Ata' bin al-Sa'ib informed us, from Abu al-Ahwas, that Ibn Mas'ud, when he would supplicate for his companions, used to say: "O Allah, guide us and make Your guidance easy for us. O Allah, facilitate us for ease and distance us from hardship, and make us among those of intellect. O Allah, grant us radiance and joy, and clothe us in sundus (fine silk) and silk, and adorn us with bracelets, O God of Truth. O Allah, make us grateful for Your favor, praising it, speaking of it, and accept our repentance, for You are the Accepting of Repentance, the Merciful."
