Abu Muslim Al-Khawlaany Ad-Daaraany.
He was the chief of the Taabi’een, and the Zaahid of his time.
Name: The correct view is that his name is ‘Abdullaah Bin Thawb, it’s also said his name is ‘Abdullaah Bin ‘Abdullaah, and (also said) ‘Abdullaah Bin Thawaab, and (also said) Ibn ‘Ubayd, and (also said) Ya’qoob Bin ‘Auf.
Birthplace: He was from Yemen.
He accepted Islaam during the time of Nabi Sallallaahu ‘Alayhi Wa Sallam, and he entered Madinah during the Khilaafah of Abu Bakr Radhiallaahu ‘Anhu.
He narrated from ‘Umar, Mu’aadh Bin Jabal, Abu ‘Ubaydah, Abu Dharr al-Ghifaari and ‘Ubaadah Bin Saamit Radhiallaahu ‘Anhum.
From those who narrated about him are: Abu Idrees al-Khawlaany, Abu ‘Aaliyah ar-Rayaaĥy, Jubayr Bin Nufayr, ‘Ataa Ibn Abi Rabaaĥ, Shurĥabeel Bin Muslim – but they did not meet him – ‘Atiyyah Bin Qays, Abu Qilaabah al-Jurmy, and Muĥammad Bin Ziyaad al-Ilhaany, and ‘Umair Bin Haany, and Yoonus Bin Maysarah, but they did not meet him, however they narrated about him.
Ismaa’eel Bin Ayyaash said: Shurĥabeel Bin Muslim related to us that Abu Muslim al-Khawlaany came to Madinah when Nabi Sallallaahu ‘Alayhi Wa Sallam had passed away, and Abu Bakr Radhiallaahu ‘Anhu was appointed (Khalifah).
Then Shurĥabeel said: Aswad al-‘Ansy in Yemen claimed to be a prophet, and he had Abu Muslim brought forth, then he made a huge fire, and threw Abu Muslim in it, but it did not harm him, so it was said to Aswad: If you do not banish this person then your followers will desert you.
So he commanded that Abu Muslim be sent out from the town on a mount, then when he came to Madinah he stopped, and he entered the Masjid to make Salaah, then ‘Umar Radhiallaahu ‘Anhu saw him and approached him and said: Where are you from? He replied: From Yemen.
So he said: What happened to that person who the imposter (Aswad) burnt with the fire? He said: He is ‘Abdullaah Bin Thawb.
Then he said: I implore you by Allaah, are you him? He replied: By Allaah, yes.
Then ‘Umar Radhiallaahu ‘Anhu embraced him and cried, then he went with him until he placed him in front of Abu Bakr Radhiallaahu ‘Anhu, then he said: All praise is due to Allaah who did not make me die until I got to see in the Ummah of Muĥammad Sallallaahu ‘Alayhi Wa Sallam a person who had something done to him which had happened to the Friend of Allaah Ibraaheem ‘Alayhis Salaam.
