Know you that Allah has made Islam the most sublime path for attainment of His supreme pleasure and the highest standards of his worship and obedience. He has favoured it with noble precepts, exalted principles, undoubtable arguments, unchallengeable supremacy and undeniable wisdom. It is up to you to maintain the eminence and dignity granted to it by the Lord, to follow it sincerely, to do justice to its articles of faith and belief, to obey implicitly its tenets and orders and to give it the proper place in your lives.
Ali ibn Abi TalibWhoever desires Paradise, proceeds towards goodness; whoever fears Hell, refrains from the impulses of passions; whoever believes firmly in death, detests wordly life; and whoever recognises the worldly life, the trials and tribulations (of life) become slight for him.
