Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) granted a concession to a person in a state of janabah that when he is about to eat something or to sleep, he may perform ablution.
Al-Tabarani recorded it. Its chain contains a narrator, Yusuf bin Khalid al-Samti, about whom Yahya bin Ma'in said: "He is a great liar, wicked, and an enemy of Allah."
