The following day they fasted again, but, like the previous day, an orphan came to the door. Once more, they forfeited their bread and ate nothing but water. The next day, they fasted for the third time. This day a captive came to their house and they repeated their charity. On the fourth day, All took Hassan and Hosain with himself to see the Prophet.
When the Prophet observed their condition; they were trembling with hunger, he said, "It grieves me to see you in this condition." Then, he stood up and walked with them. When he arrived at their home, he found Fatima praying. Her stomach was sunk in to her back- bone and her eyes had become sunken, too. The Prophet was greatly affected. At this moment Gabriel descended and said, " O, Mohammad receive this Sura.
Allah congratulates you for having such a family." And then Gabrielrecited, to him, Sura Hal-Ata.(1) (1) Al-Qadir, vol. 3, p. 107-111, Ihqaqal-Haqq, vol. 3, p. 157-171.

The word /birr/ means 'to be pious', 'just', or 'to act justly'.
It is said that making the distinction between /khayr/ and /birr/ is for the reason that the former has a general meaning of goodness while the latter has the specific meaning of 'goodness accompanied by intention'. The term /kafur/ has various meanings; one of which is 'good smelling'. Another meaning is 'fragrant plant' or a plant which has a sweet fragrance. Also, it has the common meaning of 'a sharp odor' that has medical applications, e.g. for sterilizing or disinfecting.
The other meaning has its importance as an extraordinarly white and cool substance, and it is famous, because of its coolness and whiteness.
