Hazrat Amir bin Rabi’ah narrates that I have seen the Noble Prophet (peace be upon him) using the miswak while fasting countless times. Janab Ja’far bin Muhammad, in his narration, has stated these words: (I have seen so many times) that I cannot count them or I cannot enumerate them. Imam Abu Bakr (may Allah have mercy on him) says that I am free from responsibility regarding the matter of ‘Asim. I heard Muhammad bin Yahya saying that it is not correct to make analogy upon ‘Asim bin Ubaidullah. And I heard Imam Muslim bin Hajjaj (may Allah have mercy on him) saying that we asked Imam Yahya bin Ma’in (may Allah have mercy on him), so we submitted: According to you, is Abdullah bin Muhammad bin Aqil a preferred narrator or ‘Asim bin Ubaidullah? He replied: I do not prefer either of them. Imam Abu Bakr (may Allah have mercy on him) says that I was not narrating the traditions of ‘Asim bin Ubaidullah in this book, then I saw that Imam Shu’bah and Imam Thawri have narrated from him. And Imam Yahya bin Sa’id and Imam Abdur Rahman bin Mahdi have narrated from ‘Asim through Imam Sufyan Thawri, while both of them are eminent Imams of their time. And Imam Malik (may Allah have mercy on him) has also narrated from him in his books other than“Al-Muwatta.”(That is why I have also narrated from him.)
