Hope is the Medicine which Keeps One Alive

Thabit ibn Al-Dahhak (ra) reported the Messenger of Allah (saws) to have said , "He who killed himself with anything in the world will be tormented with that very thing on the Day of Judgement."
[Bukhari]

Explanation : The common reason behind thinking of suicide is always despair , As regards the remedy of this state , I'd like to cite the following :

The remedy is hope. Allah made hopelessness unlawful by saying, "Do not despair Alah's mercy." (Surah Yusuf :87) Thus, no matter at what level of despair, depression and frustration we are, whether loss of a loved one or job , or as the result of anger from someone else m we must not give up hope as there is a ray of light at the end of the tunnel. The greatest hope is the Mercy from Allah.

Hope is the medicine which keeps one alive and going, which is when we say , hang on , we mean hang onto the thread of hope. It is not unnatural to be sad over situations and events. Even Prophet Muhammad (saws) used to be sad, looking at the plight of the Unbelievers and their rejection of his message for Oneness of Allah , and not becoming Muslims.

During dejection , there is darkness, but in hope, there is light. Therefore, one must pray for this light to illuminate the heart so that we can see beyond what is causing the suffering today.

Muslims believe that all their suffering, failures, and adversities are nothing but a test of Allah , who has said, "And surely We shall try you with something of fear and hunger, and loss of wealth and lives and crops; but give glad tidings to the steadfast , who say, when a misfortune striketh them : Lo ! To Allah we belong and yo Him we shall be returning." (Al-Baqarah)
