“There is no good deed that the son of Adam does, but between ten and seven hundred Hasanahs will be recorded for him. Allah, the mighty and sublime, said: ‘Except fasing, for it is for me and I shall reward for it. He gives up his desires and his food for my sake. Fasting is a shield, and the fasting person has two moments of joy. One when he breaks his fast and another when he meets his Lord. And the smell that comes from the mouth of the fasting person is better before Allah than the fragrance of musk.” ‘
“The Messenger of Allah said: ‘(Allah says) Every deed of the son of Adam is for him, except fasting; it is for me and I shall reward for it. Fasting is a shield. If any one of you is fasting, let him no utter obscene talk or raise his voice in anger, and if anyone insults him or wants to fight, let him say: I am fasting. By the One in whose hand is the soul of Muhammad, the smell coming from the mouth of the fasting person is better before Allah than the fragrance of musk. The fasting person has two moments of joy: When he breaks his fast he rejoices at breaking his fast and when he meets his Lord, the Mighty and Sublime, he will rejoice at having fasted.” ‘
“The Messenger of Allah said: ‘Allah, the Mighty and sublime, said: Every deed of the son of Adam is for him, except fasting; it is for me and I shall reward for it. Fasting is a shield. If any one of you is observing a fast, let him not utte obscene a fast, let him not utter obscene talk or raise his voice in anger, and if anyone insults him or wants to fight, let him say: I am a person who is fasting. By the One in Whose hand is the soul of Muhammad, the smell coming from the mouth of the fasting person is better before Allah than the fragrance of musk.” ‘ (Sahih) This Hadith was narrated from Abu Hurairah by Saeed bin Al-Musayyab.
A man got up and said: Messenger of Allah, so-and-so is my son; I had illicit intercourse with his mother in the pre-Islamic period. The Messenger of Allah (ﷺ) said: There is no unlawful claiming of paternity in Islam. What was done in pre-Islamic times has been annulled. The child is attributed to the one on whose bed it is born, and the fornicator is deprived of any right.
