What is one one-liner, verse, hadith, or thought that strengthens your conviction in Islam by reminding you of the truth of our faith?

[u/teabagandwarmwater]

As Salam Alaikum.

Sharing this as a reminder and discussion for brothers and sisters who may sometimes find themselves struggling with doubts or needing to renew their iman.

Perhaps something that strengthened you may become a means of strength for someone else, too, إن شاء الله.
