Abdur Rahman bin Harmaz al-A'araj عبد الرحمن بن هرمز الأعرج أبو داود · Fasting (Kitab Al-Siyam)

The Messenger of Allah (ﷺ) as saying: If anyone does not abandon falsehood and action is accordance with it, Allah has no need that he should abandon his food and drink. The narrator Ahmad (b. Yunus) said: I learnt the chain of narrators from Ibn Abi Dhi'b, and a man by his side made me understand the tradition. I think he was his cousin.

When one of you receives an invitation (for a meal), he should accept it. If he isn to fasting, he should eat, and if he is fasten, he should pray. Hisham said: The word salat means to pray (for him to Allah). Abu Dawud said: This tradition has also been narrated by Hafs b. Ghiyath from Hisham.
