Many places in the Holy Quran, feeding an orphan or an indigent, serving humanity is mentioned before belief in God. In other places, belief in God is followed by service to humanity. A person who shares his wealth and possessions with his needy relatives and others has a beautiful character. He does so only for the love of God without seeking a reward from people. God makes it easy for such a person to become a Muslim.
On the other hand, a person may already be a Muslim and also serving humanity. Such a Muslim is true in word and deeds. There are also many verses in the Holy Quran which speak about severe punishment and being placed in the Hellfire for those people who do not give a portion of their wealth to the needy.
The last sermon of the Prophet-peace be upon him- is known as Khutbatul Wada'. It is mentioned in almost all books of Hadith. Following Ahadith in Sahih Al-Bukhari refer to the sermon and quote part of it. See Al-Bukhari, Hadith 1623, 1626, 6361) Sahih of Imam Muslim also refers to this sermon in Hadith number 98. Imam al-Tirmidhi has mentioned this sermon in Hadith nos. 1628, 2046, 2085. Imam Ahmed bin Hanbal has given us the longest and perhaps the most complete version of this sermon in his Masnud, Hadith no. 19774.
This Khutbah of the Prophet-peace be upon him- was long and it contained much guidance and instructions on many issues. The Prophet-peace be upon him- gave this sermon in front of a large gathering of people during Hajj.
Nu’aym ibn Hammad narrates in Al-Fitan, that the 4th Caliph, Ali ibn Abi Talib said:
When you see the black flags, remain where you are and do not move your hands or your feet. Thereafter there shall appear a feeble insignificant folk. Their hearts will be like fragments of iron. They will have the state. They will fulfil neither covenant nor agreement. They will call to the truth, but they will not be people of the truth. Their names will be parental attributions, and their aliases will be derived from towns. Their hair will be free-flowing like that of women. This situation will remain until they differ among themselves. Thereafter, God will bring forth the Truth through whomever He wills.
People are asking: does this narration by Ali bin Abi Talib (k.)—that is related by Al-Bukhari’s teacher (Nu’aym bin Hamad) over one thousand two hundred years ago in his book Al-Fitan—refer to the ‘ISIS’?
Qadi Abul Hasan al-Mawardi has related a strange incident in his Alam an-Nubuwwat.
Abu Jahl was the testator of an orphan. One day, the child came to Abu Jahl in the condition that he had no shred of a garment on his body. The orphan boy implored him to have something out of his father's heritage. But the cruel Abu Jahl paid no attention to him and the poor child had to go back disappointed. The Quraish chiefs said to the boy out of fun: "Go to Muhammad (upon whom be Allah's peace and blessings) and put your complaint before him. He will recommend your case before Abu Jahl and get you your property."
