وَيَسْتَعْجِلُونَكَ بِٱلْعَذَابِ وَلَن يُخْلِفَ ٱللَّهُ وَعْدَهُۥ ۚ وَإِنَّ يَوْمًا عِندَ رَبِّكَ كَأَلْفِ سَنَةٍۢ مِّمَّا تَعُدُّونَ
And they will bid thee hasten on the Doom, and Allah faileth not His promise, but lo! a Day with Allah is as a thousand years of what ye reckon.

Sahih al-Bukhari
Funerals (Al-Janaa'iz)
Chapter: If a boy becomes a Muslim and then dies, should a funeral prayer be offered for him? Should Islam be explained to a boy?
Narrated Anas:
A young Jewish boy used to serve the Prophet (ﷺ) and he became sick. So the Prophet (ﷺ) went to visit him. He sat near his head and asked him to embrace Islam. The boy looked at his father, who was sitting there; the latter told him to obey Abul-Qasim and the boy embraced Islam. The Prophet (ﷺ) came out saying: "Praises be to Allah Who saved the boy from the Hell-fire."
