It is narrated from Hazrat Salit bin Zubayd that he heard from some of his relatives that Sayyiduna Umar bin Khattab (may Allah be pleased with him) smelled fragrance while he was in Shajrah, and Kathir bin Salit was beside him. So Sayyiduna Umar (may Allah be pleased with him) said: From whom is this fragrance coming? Kathir said: From me. I had set my hair because I did not intend to shave my head after exiting ihram. Sayyiduna Umar (may Allah be pleased with him) said: Go to the sharbah and rub and wash your head. So Kathir bin Salit did so.

Imam Malik (may Allah have mercy on him) said: Sharbah refers to that pit which is near the date-palm tree and is filled with water.
