Hadith - Tirmidhi, Narrated As-Sa’ib ibn Yazid on his father’s authority

The Prophet (peace be upon him) said, “None of you must take his brother’s staff jestingly with the intention of causing annoyance. Anyone who takes his brother’s staff must return it to him.”

Joking and Private Affection between Spouses is Encouraged

Hadith - Al-Muwatta 18.16

Yahya related to me from Malik from Abu’n-Nadr, the mawla of Umar ibn Ubaydullah that A’isha bint Talha told him that she was once with A’isha, the wife of the Prophet, may Allah bless him and grant him peace, and her husband, who was fasting, came and visited her there. (He was Abdullah ibn Abd ar-Rahman ibn Abi Bakras-Siddiq.) A’isha said to him, “What’s stopping you from coming close to your wife and kissing her and joking with her?” He said, “Can I kiss her when I am fasting?” She said, “Yes.”

Jokes should not contain falsehood

The Prophet (peace be upon him) said: I guarantee a house in the surroundings of Paradise for a man who avoids quarrelling even if he were in the right, a house in the middle of Paradise for a man who avoids lying even if he were joking, and a house in the upper part of Paradise for a man who made his character good. [Saheeh: Abu Daawood and al-Bayhaqee, authenticated by al-Albaanee in as-Saheehah]
