Mishlei (Proverbs) 4:18

He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning nor crying nor pain any more, for the former things have passed away."

Revelations 21:4

It was by some mercy of God that thou wast gentle to them; hadst thou been harsh and hard of heart, they would have scattered from about thee. So pardon them, and pray forgiveness for them, and take counsel with them in the affair; and when thou art resolved, put thy trust in God; surely God loves those who put their trust.

Al-Imran (Surah 3) 159
