Hadith 4:699
Ibn Idris narrated to us, from Abdullah bin Sa'id, who said: They mentioned the sighting of the crescent moon in Medina. And they said, "Indeed, the people of Istara have seen it." Al-Qasim and Salim said, "What do we have to do with the people of Istara?"
حدثنا بن إدريس عن عبد الله بن سعيد قال ذكروا بالمدينة رؤية الهلال وقالوا ان أهل استاره قد رأوه فقال القاسم وسالم ما لنا ولأهل استارة
