The Foundations And Concepts of Islam
A man asked the Messenger of Allaah: 'What is Islaam?'
The Messenger of Allaah answered: 'It is to surrender your heart to Allaah; and that Muslims should be safe from the harm of your tongue and hand.'
The man said: 'Which Islam is best?'
He answered: 'The Faith (Eemaan)'
He asked: 'What is Faith?'
He answered: 'To believe in Allaah, His angels, His Books, His Messengers and to believe in Resurrection after death.'
The Messenger of Allaah also said, "Islaam is to testify that there is no deity worthy of worship except Allaah and that Muhammad is the Messenger of Allaah; to observe the prayers, to give the Zakaah, to fast in the month of Ramadaan and to perform pilgrimage to the House if you are able to."
He also said, "The Muslim is the one from the evil of whose hand and tongue all Muslims are safe."
This religion – the religion of Islaam – is the one besides which Allaah accepts no other religion, not from former generations or later generations. For all Prophets were Muslims. Allaah says about Prophet Noah,
"And recite to them the news of Noah. When he said to his people: 'O my people, if my stay (with you) and my reminding you of the signs of Allaah is hard on you, then I put my trust in Allaah.'" Till He says, "…and I have been commanded to be of the Muslims."
