Abdullah bin Ukaym narrates: Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) used to make this supplication:
'Allahumma zidni imanan, wa yaqinan, wa fahman - aw qala: ilman'
(O Allah! Increase my faith, certainty, understanding (the narrator is unsure; perhaps the words are:) knowledge.)
Al-Tabarani recorded it, and its chain is jayyid (good).
