Translation
Narrated Ibn 'Abbas

Muhammad ibn 'Isa told us, Hushaym told us, Husayn informed us, on the authority of Habib ibn Abi Thabit, on the authority of Muhammad ibn Ali ibn Abd Allah ibn Abbas, on the authority of his father, on the authority of his grandfather Abd Allah ibn Abbas, who said: I spent a night with the Prophet, peace and blessings be upon him. When he awoke from his sleep, he went to his cleansing water, took his siwak and used it, and then recited these verses:

Verily, in the creation of the heavens and the earth, and in the alternation of night and day, there are indeed signs for men of understanding
until he nearly finished the surah, or finished it. Then he performed ablution, went to his prayer space, and prayed two rak'ahs. Then he returned to his bed and slept for as long as Allah willed. Then he awoke and did the same, then returned to his bed and slept. Then he awoke and did the same, then returned to his bed and slept. Then he awoke and did the same—all of that, he would use the siwak, pray two rak'ahs, and then perform Witr.

Abu Dawud said: Ibn Fudayl narrated it from Husayn, saying: He used the siwak and performed ablution while reciting:

Verily, in the creation of the heavens and the earth...
until he finished the surah.
