Faith in Allah and Attaining his Pleasure
Imam as-Sadiq (‘a) said: "My father said to me about his father (‘a) that a man from Kufah wrote to his father viz. to al-Husayn-ibn-’Ali (‘a) asking him (‘a) to imform him of the good of this world and that of the next. Then, he (‘a) wrote (in his reply): 'In the Name Allah the Beneficent, the Merciful'. After that: 'Verily, he who seeks the pleasure of Allah even while displeasing people, He suffices him in his affairs with people. But, he who seeks the pleasure of people while Allah is displeased, he leaves him to people (and he will be far from His Grace), Wassalam'."
