The Prophet ﷺ used to ask his servant, "Do you have any need?"One day, the servant said, "Messenger of Allah, I have a need."He asked, "What is your need?"He replied, "My need is that you intercede for me on the Day of Resurrection."The Prophet ﷺ asked, "Who guided you to this?"He said, "My Lord."The Prophet ﷺ said, "If that is so, then help me by making frequent prostrations."
حدثنا عفان حدثنا خالد يعني الواسطي قال حدثنا عمرو بن يحيى الأنصاري عن زياد بن أبي زياد مولى بني مخزوم
كان النبي ﷺ مما يقول للخادم ألك حاجة قال حتى كان ذات يوم فقال يا رسول الله حاجتي قال وما حاجتك قال حاجتي أن تشفع لي يوم القيامة قال ومن دلك على هذا قال ربي قال إما لا فأعني بكثرة السجود
Its isnad is sahih. Affan is Ibn Muslim, well known, previously mentioned and repeated many times. Khalid Wasiti is Ibn Abdullah, the trustworthy and firmly reliable narrator. Amr bin Yahya is Ibn Umara Mazini, a well-known trustworthy narrator who appears frequently. Ziyad bin Abu Ziyad Makhzumi, the trustworthy narrator, is not Jassas, and whoever weakened the hadith on account of him made a mistake, for that is not who he is. He was deemed trustworthy by Nasai, Bukhari, and Ibn Hibban, and he was a friend of Umar bin Abdul-Aziz, an ascetic and devoted worshipper.The hadith was mentioned before in similar wording at 15465.
