Please translate and authenticate these narrations. I'd be very grateful.
عن عمر بن الخطاب، قال: ما بقي شيء من أمر الجاهلية، غير أني لست أبالي أي المسلمين نكحت، وأيهم أنكحت 1
إن عمر بن الخطاب كان يدخل يده في دَبَرَة البعير ويقول: إني لخائف أن أسأل عما بك 2
بِسْمِ اللهِ الرَّحْمنِ الرَّحِيْم
In the name of Allah, the Most Gracious, the Most Merciful
Umar RA said, “Nothing remains from the days of ignorance except that I do not care which of the Muslims I get married to or get them married to.” It is a good (acceptable) narration.
“ʿUmar RA would put his hand on the wound of a camel and say [to it], “I am fearful that I may be asked about what has happened to you.’” It is a weak narration due to a break in the chain in between Sālim ibn ʿAbdillāh (tābiʿī) and ʿUmar RA (ṣaḥābī).
