I Asked al-Miqdad (to consult the prophet). He then narrated the tradition bearing the same meaning.

Abu Dawud said; this tradition has been reported with another chain of narrators. This version does not mention the word “testicles”.
Sunan Abi Dawud Book 1, Hadith 209
← Previous Hadith ‘Ali b abi Talib said to al-miqdad, and made a similar statement as above. Al-Miqdad asked him (the prophet). The prophet (peace be upon him) said: he should wash his penis and testicles.

Abu Dawud said : The tradition has been narrators by al-Thawri and a group of narrators from Hisham on the authority of his father from al-Miqdad, from ‘Ali reporting from the prophet (May peace be upon him).

Sunan Abi Dawud Book 1, Hadith 208 Next Hadith → I felt greatly distressed by the frequent flowing of prostatic fluid. For this reason I used to take a bath very often. I asked the apostle of Allah (ﷺ) about this. He replied: Ablution will be sufficient for you because of this. I asked: Messenger of Allah, what should I do if it smears my clothes. He replied: It is sufficient if you take a handful of water and sprinkle it on your clothe when you find it has smeared it.
