Ibn `Umar narrated that:
the Prophet (ﷺ) said: "Salat will not be accepted without purification, nor Charity from Ghulul." Hannad said in his narration, "except with purification" [Abu `Eisa said: This Hadith is the most correct thing on this topic, and the best. There are also narrations on this topic from Abu Al-Malih, from his father; and Abu Hurairah and Anas. And Abu Al-Malih bin Usamah's name is `Amir, and they also say it was Zaid bin Usamah bin `Umair Al-Hudhali.
