Musannaf Ibn Abi Shaybah 44 — Keeping up ablution and its virtue

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) asked the Companions: "Shall I not tell you of something by which Allah Almighty forgives sins and increases good deeds?" It was said: "Certainly, please tell us." The Prophet (peace and blessings be upon him) said: "Performing ablution fully in difficult times, and taking many steps towards the mosque."
