Nafusa and the souls of his companions went to Sijilmasa, settled there, and asked its people for zakat. They refused them. Then the master of Sijilmasa came to them and fought them, but they defeated him, killed him, and entered Sijilmasa and took control of it. This was in the year 453 AH. Yusuf ibn Tashfin, who was his cousin, was appointed over it. Al-Afir Burur returned to the desert. Yusuf collected the zakat from the subjects and took only the zakat from them, staying in the desert for a period. Then Abu Bakr ibn Umar returned to Sijilmasa with a group, establishing the Sunnah, the sermon, the command, and plunder. He appointed his brother Abu Bakr ibn Ibrahim ibn Umar over it. He equipped Yusuf ibn Tashfin with the armies of the Almoravids to the Sous, uniting under his hand. Yusuf was religious, firm, wise, experienced, and they persisted in this until the year 462 AH. Abu Bakr ibn Umar Al-Hajjar took charge, and the groups of the Almohads united under Yusuf ibn Tashfin, and they made him their ruler and gave him the title "Commander of the Faithful." The state in the Maghreb belonged to the Zenata, who had revolted during the interregnum. It was a bad, condemned state, neither grateful for blessings nor religious. The Commander of the Faithful and his followers were appointed to follow the Sunnah and the pure Sharia. The people of the West sought their help, so Yusuf the aforementioned marched to them and conquered it, fortress after fortress, and land after land, with ease. The word of God was loved by the subjects, and their affairs were obeyed. Then he intended the place of the city of Marrakech, which was at that time a barren plain, for settlement and cultivation. It was a central location in the land of the Arabs, like Aghbarwan, under the land of the Masamida, who are the strongest of the Arabs in power and their stronghold. So he laid out the city of Marrakech there to suppress the mountain dwellers if they intended to rebel, and he made it a home and a base. He did not allow anyone to oppose him and took control of the lands connected to the Hijaz, such as Sabta, Tangier, Salé, and others. His armies increased, and a group of the Lamtuna, a tribe, and others from the desert emerged, and they joined them because of their need. Before, they used to wear veils that covered them from the heat and cold, as the Arabs do. The prevailing color of their clothes was black, and perhaps when they conquered the lands, they tightened the veils. There is disagreement about the reason for their wearing veils. It is said that it was a remnant of the Lamtuna who went out on a raid against their enemy. When they entered the enemy's homes, they found only old men, children, and women. When the old men were killed by the enemy, they ordered the women to wear the clothes of men and to veil themselves and put on armor, so that they would not be recognized. They put on weapons and the old men and children marched before them. Then the poets sang about the houses, making the enemy think that they were a great army. The enemy thought that these were warriors fighting. So they said, "Death is the best opinion. Let us drive the camels and attack them. If they prevent us, we will fight them." So the war between them was decided. The enemy was surrounded by the army. The men of the tribe came out, and the enemy was between them and the women. They fought, and their enemy killed a large number of them.
