craving: hajj and ummrah
"Verily in the remembrance of Allah do hearts find rest" (Quran Surah 13 :The Thunder, 28th verse)
Trials are sent to better us.
There were scientific facts mentioned in the Quran that modern science has only recently (1-100 years ago) found to be true.
Looking for tranquillity? Then why wait?
Science can tell us how things came to be, but it can't tell us why. If you're searching for your purpose, look no further.
Allah does not place a burden on a soul with more than it can bear.
