সুনানে ইবনে মাজাহ ৩১৬৭

It was narrated that Nubaishah said:“A man called the Messenger of Allah (ﷺ) and said: ‘O Messenger of Allah, we used to sacrifice the ‘Atirah during the Ignorance days in Rajab,; what do you command us to do?’ He said: “Sacrifice to Allah whatever month it is, do good for the sake of Allah and feed (the poor).’ They said: ‘O Messenger of Allah, we used to sacrifice the Far’ah during the Ignorance days; what do you command us to do?’ He said: ‘For every Sa’imah* (flock of grazing animals), feed the firstborn as you feed the rest of your flock until it reaches an age where it could be used to carry loads, then sacrifice it, and give its meat in charity’ – I** think he said – ‘to the wayfarer, for that is good.’”
