Mukhtasar Muslim

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) went to the toilet (to relieve himself), so I placed water for ablution for him. When he came out, he asked, "Who placed this water?" The people or I said, "Ibn Abbas did." The Prophet (peace and blessings be upon him) said, "O Allah! Grant him understanding of the religion."
