The Messenger of Allah ﷺ said, "O Allah, whoever believes in me, affirms my truthfulness, and knows that what I have brought is the truth from You, reduce his wealth and children, make him love meeting You, and hasten his appointed end. And whoever does not believe in me, does not affirm my truthfulness, and does not know that what I have brought is the truth from You, increase his wealth and children, and prolong his life."
حدثنا هشام بن عمار حدثنا صدقة بن خالد حدثنا يزيد بن أبي مريم عن أبي عبيد الله مسلم بن مشكم
قال رسول الله ﷺ اللهم من آمن بي وصدقني وعلم أن ما جئت به هو الحق من عندك فأقلل ماله وولده وحبب إليه لقاءك وعجل له القضاء ومن لم يؤمن بي ولم يصدقني ولم يعلم أن ما جئت به هو الحق من عندك فأكثر ماله وولده وأطل عمره

Its isnad is daif. Tabarani narrated it, 31/17, hadith 56, from the hadith of Hisham, and Mualla bin Mansur corroborated him (Usdul-Ghabah, 4/125). Amr bin Ghaylan's companionship is disputed, and Dhahabi said, "His companionship is not established."
