Shama-il Tirmidhi Chapter 024, Hadith Number 001 (135).
'Aayeshah Radiyallahu 'Anha says: "Till the demise of Rasulullah sallallahu'Alayhi Wasallam, his family never ate a full stomach of bread made of barley for two consecutive days".
It is Possible that they may have eaten a full stomach of dates, but not of bread, where they did not eat it for two consecutive days. A question may arise, that it is evident from the ahadith that Sayidinah Rasulullah Sallalahu 'Alayhi Wasallam gave his wives their expenses for a year.
There seems to be a contradiction between the two ahaadith the 'ulama have explained it in various ways. Among these, one explanation is that, in the hadith the word 'Ahl' (family) is extra and means that the expenses were for himself. It also shows that he did not have any other provisions. A narration is related on this topic from Sayyiditina 'Aayeshah Radiyallahu 'Anha at the end of the chapter. Some 'ulama have explained it in this manner, that he gave his wives provision, but they also, in wanting to gain thawaab (reward), gave it away in charity. According to this humble servant there are two other explanations that may be possible. Since it is not taken from the sayings of the great learned, it cannot be taken as an argument or proof, but can surely be assumed. The first is that the yearly expenses were only that much, that they did not cover the cost of continuously eating bread for two consecutive days, but of eating bread sometimes, dates sometimes, and at times remaining hungry. The second is that it may have been in the form of dates. This is not denied in this hadith but that of eating bread is.
