English translation
1429. It was reported from Yunūs bin 'Ubaid, from Al-Ḥasan, that 'Umar bin Al-Khaṭṭāb gathered the people behind Ubayy bin Ka'b (in the month of Ramaḍān.) He led them for twenty nights; he would not pray the Qunūt except in the last half (of the month). When the last ten nights would start, he would not lead them, and instead pray in his house. So they would say, 'Ubayy has fled (like a slave)!" (Ḍa'if) Abū Dāwūd said: This shows that what was mentioned regarding the Qunūt is not correct. And these two Ḥadīths show the weakness of the Ḥadīth narrated from Ubayy that the Prophet ﷺ would perform Qunūt in the Witr.
