Hum se Muhammad bin Yahya ne bayan kiya, kaha hum ko Attab bin Basheer ne khabar di, unhein Ishaq ne, in se Zuhri ne bayan kiya ke mujhko Ubaidullah bin Abdullah ne khabar di ke Umm Qays bint Muhsan jo pehle pehal Hijrat karne wali auraton mein se thien jinhon ne Rasool Allah salla Allahu alaihi wasallam se bai-at ki thi aur woh Ukashah bin Muhsan razi Allahu anhu ki behen thien, khabar di ke woh Rasool Allah salla Allahu alaihi wasallam ki khidmat mein apne بیٹے ko le kar hazir huien. Unhon ne is bache ka kauwa girne mein taloo daba kar ilaaj kiya tha. Nabi Karim salla Allahu alaihi wasallam ne farmaya ke Allah se dro ke tum apni aulad ko is tarah taloo daba kar takleef pahunchati ho ood e hindi (koot) is mein istemal karo kyunke is mein saat beemariyon ke liye shifa hai jin mein se ek namonia bhi hai. Nabi Karim salla Allahu alaihi wasallam ki murad ood e hindi se «kust» thi jise «qust» bhi kehte hain yeh bhi ek lughat hai.
