Sayyiduna Khalid bin Walid (may Allah be pleased with him) says: When the land of Sham presented its blessings before us, including wheat and honey, the Commander of the Faithful, Sayyiduna Umar bin Khattab (may Allah be pleased with him), ordered me to set out towards Hind. In those days, by Hind we used to mean Basra. I was disinclined towards this expedition. Meanwhile, a man stood up and said to me: Abu Sulaiman! Fear Allah, the tribulations have already appeared. From the other side, another man said: The tribulations have not yet appeared, because Ibn Khattab (may Allah be pleased with him) is still alive; the tribulations will come after him. (And in the era of tribulations) when people will be at the place of Bilyan (located beyond Yemen), then a man will look around at the circumstances and ponder whether there is any place where such tribulations do not exist as in this place, but he will not find any such peaceful place. This is the very time about which the Messenger of Allah (peace and blessings be upon him) said that before the Day of Judgment there will be widespread killing, and we seek refuge with Allah that such a time should not befall us or you.
