Narrated It was narrated that Ma'dan bin Abi Talhah said:
'Umar said: I never asked the Messenger of Allah ﷺ about anything more than I asked him about kalalah, until he poked me in the chest with his finger and said: `Is not ayatus-saif (the verse of summer, i.e., it was revealed in summer), which appears at the end of Sooratan-Nisa', sufficient for you?”
Narrated It was narrated that ‘Abdullah, the freed slave of Asma’ bint Abi Bakr, said:
Asma’ sent me to 'Abdullah bin 'Umar, and she said: I have heard that you regard three things as haram: borders on garments, saddle cloths made of bright red cloth, and fasting the whole of Rajab. 'Abdullah said to me: As for what you have mentioned about Rajab, what about one who fasts continually? As for what you said about borders on garments, I heard 'Umar bin al-Khattab say: I heard the Messenger of Allah ﷺ say: “Whoever wears silk in this world will not wear it in the Hereafter.`
