A man observed the Prophet ﷺ while he was praying, and he was saying in his prayer, "O Allah, forgive me my sin, grant me spaciousness in my home, and bless me in what You have provided me."
قال حدثنا حجاج قال حدثنا شعبة عن سعيد الجريري قال سمعت عبيد بن القعقاع يحدث
رمق رجل النبي ﷺ وهو يصلي فجعل يقول في صلاته اللهم اغفر لي ذنبي ووسع لي في داري وبارك لي فيما رزقتني
Its isnad is daif due to the obscurity of Ubayd bin Qaqa. Haythami said, 10/110, "I do not know him." Ibn Hajar said in Tajeel, "The correct name is Humayd bin Qaqa," but he too considered him unknown.Tirmidhi narrated the hadith with similar wording from Jareeri, from Abu Saleel, from Abu Hurairah, that a man said, "O Messenger of Allah, I heard your supplication last night, you were saying, 'O Allah, forgive me my sin, make my provision plentiful for me, and bless me in what You have provided for me.'" ﷺ said to him, "Do you think they left anything out?" But Tirmidhi said, "Rare."
