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."
Sahih al-Bukhari Book 78, Hadith 135
← Previous Hadith Allah's Messenger (ﷺ) said: "Whoever amongst you swears, (saying by error) in his oath 'By Al-Lat and Al- Uzza', then he should say, 'None has the right to be worshipped but Allah.' And whoever says to his companions, 'Come let me gamble' with you, then he must give something in charity (as an expiation for such a sin)." (See Hadith No. 645)

Sahih al-Bukhari Book 78, Hadith 134 Next Hadith → The Prophet (ﷺ) entered upon me while there was a curtain having pictures (of animals) in the house. His face got red with anger, and then he got hold of the curtain and tore it into pieces. The Prophet (ﷺ) said, "Such people as paint these pictures will receive the severest punishment on the Day of Resurrection ."
