Musnad Ahmad Hadith 26689

It is narrated from Umm Salamah (may Allah be pleased with her) that the Prophet (ﷺ) said: At the time of the death of a caliph, there will be disagreement among the people regarding the new caliph. At that moment, a man will flee from Madinah Munawwarah to Makkah Mukarramah. Some people from among the people of Makkah will come to him and, against his will, will bring him out and pledge allegiance to him between the Black Stone and the Station of Ibrahim. Then, an army from Syria will be sent to fight them, but it will be swallowed up at the place of Bayda. When people see this, the Abdal of Syria and the groups of the pious (a rank among the saints) will come to him and pledge allegiance to him. Then, a man from the Quraysh will come forward whose maternal uncles will be from Banu Kalb. The man from Makkah will send an army against this Qurayshi, which will prevail over him. This army or battle will be called Ba’th Kalb. The person who is not present at the distribution of the spoils of this battle will be deprived. He will distribute wealth and act according to the Sunnah of the Prophet (ﷺ), and Islam will spread its neck over the earth, and that man will remain on the earth for nine years.
