The noble prophet, Mohammad (S.A.W) said: ‘’he who affirms that there is no god but Allah, He is one and has no associate and that Mohammad is his servant and messenger, that Christ is servant and the son of His slave girl and he - Christ is His communicated (bestowed) word to Mary, that paradise is a fact and hell is fact. Allah would make him enter paradise through any of its (paradise) door.”
Book 1, Hadith 4, Sahih Muslim
Dear brethren, the hadith above affirms to us the great reward (garden of paradise) that awaits the believers. Some essential aspects of belief are also stated therein e.g. in the oneness of Allah, the prophethood of Muhammad, the existence of heaven and hell, and even the prophethood of Jesus Christ. It is however incumbent on us to equally strengthen our faith and follow His injunctions.
