1] Characteristics of a Faithful: It's only beseeming for the faithful that he should be sound of faith and a man of conviction. His knowledge entails forbearance as moderation is an adornment for the learned. He is wise but soft-hearted; well-dressed and restrained in order to conceal his indigence; never prodigal even if a man of substance; charitable and compassionate to the destitute; large-hearted and generous in giving to the kinsfolk their due; strenuous and unflinching in provided justice to others; never crosses the prescribed limits in favouring his near and dear ones nor does he find fault or cull out the errors of those whom he dislikes. A Muslim is indifferent to reviling and taunting, frolics and sports, decrials and backbiting. He never runs after what is not his right nor denies what he owes to others... Humble and submissive, devoted and enchanted, as a faithful is in his prayers, he is a messenger of cheer; his endurance is owing to the awe of God; his silence is for meditation and reflection; he pays attention for edification and instruction; he seeks company of the learned for acquiring knowledge; keeps mum to avoid transgression; and if he speaks, he speaks to spread the virtue.... - Hasan Al-Basri 2] Prostration of Gratitude: When the Messenger of Allah, peace be upon him, used to receive good news, he would prostrate (sujud) himself and give thanks to Allah. Abdur Rahman ibn Awf, may Allah be pleased with him, narrated: "The Prophet entered upon us in the mosque, stood facing the qiblah, then prostrated himself and remained in sujud for a long time. I said to him: 'O Messenger of Allah, you prostrated yourself for such a long time that we thought Allah had taken your soul.' He said: 'Jibril came to me with good news. He told me: "Allah says, 'Whoever sends blessings on you, I will send sixty blessings on him in return, and whoever salutes you, I will salute him in return.'" so I prostrated myself and gave thanks to Allah."
