'Abdullah bin Mas'ud (May Allah be pleased with him) reported: There were, about forty of us with Messenger of Allah ﷺ in a camp when he said, "Aren't you pleased that you will constitute one-fourth of the inhabitants of Jannah?" We said, "Yes". He again said, "Aren't you pleased that you will constitute one-third of the inhabitants of Jannah?". We said: "Yes". Upon this he ﷺ said, "By Him in Whose Hand Muhammad's soul is, I hope that you will constitute one-half of the inhabitants of Jannah; and the reason is that only Muslims will be admitted into Jannah; and you are no more compared to the polytheists than as a white hair on the skin of a black ox, or a black hair on the skin of a white ox". Al-Bukhari and Muslim.
This hadith teaches us about how much reward awaits us if we devote ourselves completely to Allah and His Messenger. We should strive hard to do good deeds so we can attain this great blessing from our Lord. We should also remember that polytheists have no share in this reward; thus we must stay away from any kind of disbelief or idolatry so we can be among those who enter Paradise without any fear or worry.
