Hadith 37:95
Abu Usama narrated to us, he said: Hisham bin Hassan narrated to us, from Muhammad, he said: Abu Mas’ud al-Ansari entered upon Hudhayfah during his illness in which he died, so he embraced him and said: "The separation." He said: "Yes, a beloved one who has come during a time of need. Is it not that he who regrets has succeeded? Is it not after what I know of certainty?"
حدثنا أبو أسامة قال حدثنا هشام بن حسان عن محمد قال دخل أبو مسعود الأنصاري على حذيفة في مرضه الذي مات فيه فاعتنقه فقال الفراق فقال نعم حبيب جاء على فاقة ألا أفلح من ندم أليس بعد ما أعلم من اليقين
