Be confident that Allah knows what is best for you: You should place your trust in Allah and must remember that you do not know the wisdom behind this trial, perhaps it will make you stronger and lead you on a path to a better life. We should never limit Allah’s wisdom to our comprehension level, because we will never be able to comprehend it — it is above our capability to understand. We should, however, know for a certainty that Allah does not intend harm because it is harmful. Harm with Allah is not intended for itself but for other things that may bring good.

Ibn Uthaymeen, may Allah have mercy upon him, said: “Allah doesn’t particularly intend harm for a person when He causes him to become ill. Allah intends for the disease to take place and the disease is what may harm man. But He did not intend harm for man. He intends for him only the good from it. Sometimes, the Divine Wisdom may be apparent to the sick, and sometimes it may not. As Allah has said (what means): “And fear a trial which will not strike those who have wronged among you exclusively, and know that Allah is severe in penalty.” [Quran 8:25]

Remember Allah and ask Him for forgiveness much: Ali said: “When Allah guides His servants to ask for forgiveness, He helps them to achieve what they request.” Allah has said (what means): “But Allah would not punish them while you are amongst them. And Allah would not punish them while they seek forgiveness.” [Quran 8:33]

Allah has told us that He would not punish someone who seeks forgiveness, because sincere forgiveness removes the sin that is the reason for the punishment. The Prophet said: “He who is constant in seeking forgiveness, Allah will make for him a way out of any distress, release from grief, and provide for him from where he does not expect it.” [Abu Dawood and Ibn Majah] So whoever believes in Allah alone and seeks forgiveness from Him, He will provide for him an appointed term, and whoever does good after that, He will increase him from His Grace.

A believer always strives for the pleasure of his Lord and does not stop because of disease or a trial. The best example is the example the scholar of this nation; Ibn 'Abbas when he lost his vision and said: “If Allah has taken from my eyes their light, it is in my tongue and heart that I will find the light. My heart is bright and my mind has no defects. And in my mouth there is a sharp, authentic sword.”
