Mukhtasar Muslim (Abridged) 1903 — Saying tasbih after Fajr prayer

Abu Huraira (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said: Whoever says "Subhan Allah wa bihamdihi" one hundred times in the morning and in the evening, no one will come on the Day of Resurrection with a deed better than his, except one who says as much or more than this.
