BAYHAQI 4044:
from Zir b. Ḥubaysh —
I asked Ubai bin Kaʿb regarding the two Muwwidhat (Surats of taking refuge with Allah). He said, "I asked the Prophet ﷺ about them, He said, 'These two Surats have been recited to me and I have recited them (and are present in the Qur'an).' So, we say as Messenger of Allah ﷺ said (i.e., they are part of the Qur'an." (Using translation from Bukhārī 4976)

عن زر بن حبيسه —
سَأَلْتُ أُبَيَّ بْنَ كَعْبٍ عَنِ الْمُعَوِّذَتَيْنِ فَقَالَ سَأَلْتُ رَسُولَ اللهِ ﷺ عَنِ الْمُعَوِّذَتَيْنِ فَقَالَ قِيلَ لِي فَقُلْتُ فَنَحْنُ نَقُولُ كَمَا قَالَ رَسُولُ اللهِ ﷺ
