Faith is trust. Faith is hope. Faith is belief.
All in the goodness or trustworthiness of a person, concept or entity.
"Believing in Islam is like believing in the sun rising. Not because we can see it, but because by it, we can see everything."
Allah withheld the gift of faith from some of the closest relatives of His Messengers like Muhammad's uncle, Ibrahim's father, and Noah's son. Yet He blesses us with the most valuable gift ever since our very first breath. and that is Islam! Hence, let us safeguard it and renew our faith all the time, before we meet our Lord sooner or later in the state of the purest soul insyaAllah Taala...
We may not always understand why Allah allows certain things to happen, but we can be certain that Allah is not making any mistakes! For instance, when Allah subjects us to adversity, He is opening our eyes to reality. Allah is allowing us to change our bad habits in order to appreciate life to the fullest, to give us the opportunity to repent for past sins and correct our future actions, eventually to raise our status in the hereafter insyaAllah ameen ya Rabb.
May He always guide us and give us strength to go on with life and be blessed by Allah.
