Narrated It was narrated from Ibn 'Umar that 'Umar bin al-Khattab addressed us in al-Jabiyah, and said:
The Messenger of Allah ﷺ stood before us as I am standing before you, and said: `I urge you to show respect to my Companions, then those who come after them, then those who come after them, then lying will become so widespread that a man will start to give testimony before he is asked to do so.Whoever among you wants to attain a spacious abode in Paradise, let him adhere to the jama'ah (main body of Muslims), for the Shaitan is with the one who is alone, but he is further away from two. And no one of you should be alone with a woman for the Shaitan will be the third one present. The one who is pleased with his good deeds and upset by his bad deeds is a believer.`
It was narrated from ʼUmar bin al-Khattab رضي الله عنه and Hudhaifah bin al-Yaman رضي الله عنه that the Prophet ﷺ did not take zakah on horses or slaves.
Narrated Abdullah bin 'Umar narrated that 'Umar bin al-Khattab said:
I heard the Messenger of Allah ﷺ say: “Allah, may He be glorified and exalted, forbids you to swear by your fathers,` 'Umar said: By Allah, I never swore by them since I heard the Messenger of Allah ﷺ forbid it, and I never uttered (such words) whether I was swearing an oath or describing someone else doing so.
