Sahih al-bukhari:1387 Chapter: What is said about funerals, and those whose last words were: La ilãha ilallãh (none has the right to be worshipped but Allah) Book 23, Hadith 139

Narrated Hisham’s father: Aisha said, “I went to Abu Bakr (during his fatal illness) and he asked me, ‘In how many garments
was the Prophet (ﷺ) shrouded?’ She replied, ‘In three Suhuliya pieces of white cloth of cotton, and there
was neither a shirt nor a turban among them.’ Abu Bakr further asked her, ‘On which day did the
Prophet die?’ She replied, ‘He died on Monday.’ He asked, ‘What is today?’ She replied, ‘Today is
Monday.’ He added, ‘I hope I shall die sometime between this morning and tonight.’ Then he looked at
a garment that he was wearing during his illness and it had some stains of saffron. Then he said, ‘Wash
this garment of mine and add two more garments and shroud me in them.’ I said, ‘This is worn out.’ He
said, ‘A living person has more right to wear new clothes than a dead one; the shroud is only for the
body’s pus.’ He did not die till it was the night of Tuesday and was buried before the morning.”
