(6) باب كَيْفَ التَّكَشُّفُ عِنْدَ الْحَاجَةِ
Narrated Abdullah ibn Umar:
When the Prophet (ﷺ) wanted to relieve himself, he would not raise his garment, until he lowered himself near the ground.Abu DAwud said: This tradition has been transmitted by 'Abd al-Salam b. Harb on the authority of al-A'mash from Anas b. Malik. This chain of narrators is weak (because A'mash's hearing tradition from Anas b. Malik is not established).
