Sunan ibn Mājah Ḥadīth [3663] – The Father is the Middle Door to Paradise
It is narrated on the authority of Abī Dardā' (may Allāh be pleased with him) that he heard the Prophet (peace and blessings of Allāh be upon him) say: “The father is the middle door of Paradise (i.e., the best way to Paradise), so it is up to you whether you take advantage of it or not.”
Commentary by Dārussalām added.
