The Messenger of Allah ﷺ said, "There is no servant who raises his hands until his armpits are visible, asking Allah for something, except that Allah grants it to him, as long as he is not hasty."They asked, "Messenger of Allah, what does it mean to be hasty?"He replied, "He says, 'I have asked again and again, but I have not been given anything.'"Zuhri narrated this hadith from Abu Ubayd, the freedman of Ibn Azhar, from Abu Hurairah, from the Prophet ﷺ, who said, "The supplication of one of you will be answered as long as he is not hasty, saying, 'I prayed but my prayer was not answered.'"
حدثنا يحيى أخبرنا يعلى بن عبيد قال أخبرنا يحيى بن عبيد الله عن أبيه
قال رسول الله ﷺ ما من عبد يرفع يديه حتى يبدو إبطه يسأل الله مسألة إلا آتاها إياه ما لم يعجل قالوا يا رسول الله وكيف عجلته قال يقول قد سألت وسألت ولم أعط شيئا وروى هذا الحديث الزهري عن أبي عبيد مولى ابن أزهر عن أبي هريرة عن النبي ﷺ قال يستجاب لأحدكم ما لم يعجل يقول دعوت فلم يستجب لي
[Its chain is daif] Yahya bin Ubaydullah and his father are both daif. The hadith, "A request will be answered for one of you..." to the end, is agreed upon (by Bukhari and Muslim) and was mentioned previously at 3387.
