We have enjoined on man Kindness to his parents: in pain did his mother bear him, and in pain did she give him birth. The carrying of the (child) to his weaning is (a period of) thirty months. At length, when he reaches the age of full strength and attains forty years, he says "O my Lord! Grant me that I may be grateful for Thy favour which Thou hast bestowed upon me, and upon both my parents, and that I may work righteousness such as Thou mayest approve; and be gracious to me in my issue. Truly have I turned to Thee and truly do I bow (to Thee) in Islam." (15) Surah Ahqaaf
Allah's Apostle (p.b.u.h) said, "Anyone who takes a bath on Friday and cleans himself as much as he can and puts oil (on his hair) or scents himself; and then proceeds for the prayer and does not force his way between two persons (assembled in the mosque for the Friday prayer), and prays as much as is written for him and remains quiet when the Imam delivers the Khutba, all his sins in between the present and the last Friday will be forgiven."
