Tirmidhi

‘Abdullah bin Abbas (may Allah be pleased with them both) narrates that when the Prophet (peace and blessings of Allah be upon him) used to drink, he would drink in two breaths. © Imam Tirmidhi says:
1- This hadith is gharib,
2- We know it only from the narration of Rushdein bin Kuraib,
3- I asked Abu Muhammad Abdullah bin Abdur Rahman Darimi about Rushdein bin Kuraib, saying: Is he stronger or Muhammad bin Kuraib? He said: Both are very close (in rank), and in my view, Rushdein bin Kuraib is more preferred,
4- I asked Muhammad bin Ismail Bukhari about him, and he said: Muhammad bin Kuraib is more preferred than Rushdein bin Kuraib,
5- In my view, the statement of Abu Muhammad Abdullah bin Abdur Rahman Darimi is more correct that Rushdein bin Kuraib is more preferred and greater; he met Ibn Abbas and saw him. These two are brothers, and from both of them, munkar ahadith are also narrated.
