Qatada reported: I heard Abe 'Uthman al-Nahdi as saying: There came to us a letter of 'Umar as we were in Adharba'ijan or in Syria in the company of 'Utba bin Farqad (and the letter ran thus): After (usual praise and glorification of Allah) it is stated that Allah's Messenger ( صلی اللہ علیہ وسلم ) has forbidden the use of silk btit to the extent of these two fingers, and Abu 'Uthman said: We at once understood by these words that he meant (silk) patterns on (the cloth).
