You shall certainly travel from stage to stage.Al-Bukhari recorded from Mujahid that Ibn Abbas said,"Stage after stage. Your Prophet has said this."Al-Bukhari recorded this statement with this wording. Ikrimah said, طَبَقاً عَن طَبقٍ (From stage to stage). "Stage after stage. Weaned after he was breast feeding, and an old man after he was a young man."Al-Hasan Al-Basri said, طَبَقاً عَن طَبقٍ(From stage to stage)."Stage after stage.- Ease after difficulty,- difficulty after ease,- wealth after poverty,- poverty after wealth,- health after sickness, and- sickness after health."The Disapproval of Their Lack of Faith, giving Them Tidings of the Torment, and that the Ultimate Pleasure will be for the Believers Allah said,فَمَا لَهُمْ لَا يُوْمِنُونَ
