“There is no person who kills a small bird or anything larger, for no just reason, but Allah will ask him about it.” It was said: “O Messenger of Allah, what does ‘just reason mean?” He said: “That you slaughters it and eat it, and o not cut off its head and throw it aside,”
I heard Messenger of Allah (ﷺ) say: But between them are certain doubtful things which many people do not recognize. He who guards against doubtful things keeps his religion and his honor blameless, but he who falls into doubtful things falls into what is unlawful.
the Messenger of Allah (ﷺ) stood up on the Day of the conquest of Makkah, on the steps of the Ka’bah. He praised and glorified Allah (SWT), then he said: “Praise is to Allah (SWT) who has fulfilled His promise, granted victory to His slave and defeated the Confederates alone. The one who is killed by mistake is the one who is killed with a whip or a stick; for him the blood money is one hundred camels, of which forty should be pregnant she-camels with their youngs in their wombs. Every custom of Ignorance period, and every blood claim, is beneath these two feet of mine (i.e. is abolished), except for the custodianship of the Ka’bah and the provision of water for the pilgrims, which I confirm still belong to the people to whom they belonged before.”
