Chapter: Whoever does not consider as Kafir the person who says that...
Narrated Ibn `Umar:
that he found `Umar bin Al-Khattab in a group of people and he was swearing by his father. So Allah's Messenger (ﷺ) called them, saying, "Verily! Allah forbids you to swear by your fathers. If one has to take an oath, he should swear by Allah or otherwise keep quiet."
