The Meaning of Sacrifice
Tadhiyah linguistically: is the verbal noun of dahha. It is said: “Dahha bi-nafsihi aw bi-`amalihi aw bi-malihi (He sacrificed himself, his work, or his wealth): if one expends it and gives it without return. It is novel in this meaning.  al-Mu`jam al-Wasit (1/535); al-Mu`jam al-Wajiz (p. 377).
Tadhiyah technically: is expending the self, time, or wealth for a higher cause and a more desired purpose, all the while hoping for reward from Allah, honoured and majestic. A synonym of it is fida’. From its meanings are expansion and struggle.Commandments of Sacrifice and Encouragement towards it in the Qur’an and Sunnah
❖ Allah, exalted, says: “For Him to choose martyrs from among you.” Al `Imran: 140. al-Qasami said: “Meaning, so that He may honour from among you some with martyrdom, so that they are an example for others in sacrificing the self for the sake of truth, dying for its cause, elevating its status.”  Tafsir al-Qasimi (2/419).

❖ The Prophet ﷺ used to be the best of people, the most generous of people, and the most courageous of people. The people of Madinah were stunned by a sound on some night. People went towards the sound, only to see the Prophet ﷺ returning therefrom, having beaten them to it. He was riding a steed that belonged to Abu Talhah unsaddled, with the sword around his neck. He said: “Do not be stunned.”  Reported by al-Bukhari (2908) and Muslim (2307), and this is his wording. Meaning there is nothing to be worried about, so be calm.
❖ Anas ibn Malik, Allah be pleased with him, said: “Abu Talhah was the wealthiest among the Supporters in terms of palm trees in Madinah, and what he loved most among his possessions was his garden known as Bairuha’ which was opposite the mosque. The Messenger of Allah ﷺ often visited it and drank from its fresh water. When the verse was revealed: “You will not attain righteousness until you spend of that which you love,” Al `Imran: 92, Abu Talhah came to the Messenger of Allah ﷺ and said: “Allah says in His Book: “You will not attain righteousness until you spend of that which you love,” and the dearest of my property is Bairuha’, so I have given it as charity for Allah’s sake, and I anticipate its reward with Him; so spend it, Messenger of Allah, as Allah guides you.” The Messenger of Allah ﷺ said: “Well! That is surely a profitable transaction. I have heard what you said, and I think you should spend it on your nearest relatives.” So, Abu Talhah distributed it among nearest relatives and cousins.”  Reported by al-Bukhari (1461), and this is his wording, and Muslim (998).
