Prophet Muhammad, sallallaahu ‘alayhi wa sallam, reminded us through his guidance and example, that Islam is complete submission to the will of Allah. For one who submits, a mere declaration or display of belief will not be taken for success, but his or her heart and soul will certainly be put to test.
Allah tested the Prophet of Allah, sallallaahu ‘alayhi wa sallam, severely in order that he, sallallaahu ‘alayhi wa sallam, becomes an example for his Companions to follow. Similarly, He tests the believer to see whether helives a righteous life (in accordance with the instructions and commands set by Allah) or lives according to what his desires dictate; whether the faith he displays is firmly rooted in his heart or is it merely on the surface. He will be tested to see whether he will continue to have faith and love of Allah when in calamity as he does when in comfort; whether he will continue to remember and worship Him if given bounties and comforts of life as he does when he lives a modest life. Allah will undoubtedly test him to see if his faith, trust, and love of Him is unconditional or is it conditioned upon good health and a comfortable life free from stress and anxiety.
The Prophet of Allah, sallallaahu ‘alayhi wa sallam, showed us through his own example that for a righteous Muslim, this life is a testing ground where he will continue to be tested until he meets Allah. For him, tests will be conducted on earth while he lives, and not after he dies. He knows that as soon as death arrives and he steps into the next world, his tests are over. There, he only receives the results of his tests, and enjoys the fruits of his deeds that he committed during a short span of time called Life.
