The Messenger of Allah (SAW) once visited an Arab (villager). He received him very well and respected Prophet Muhammad (SAW) very much. The Prophet (SAW) was very happy and said to him, O Arab ask what you want! He said, Messenger of Allah, a she-camel with her saddle and a few sheep whose milk would satisfy my family members. He made this request twice. The Messenger of Allah (SAW) said, Was it not possible for you to ask me as the old woman of the Bani Israel asked Musa?
The Companions (RA) asked him, O Messenger of Allah! What is the story of the old woman of the Bani Israel? He said to them, Musa (AS) decided to emigrate with the Bani Israel but he got lost on the way. So, their scholars said to him, We tell you that Yusuf (AS) had got our ancestors to promise that we would not go away from Egypt unless we took his bones with us. Perhaps, we are lost because we have not fulfilled the promise. Musa (AS) asked them who among them could point out his grave.
They said that none apart from an old woman of the Bani Israel could point out the grave. Musa (AS) sent a messenger to fetch her and requested her to guide them to the grave of Yusuf (AS). She said, "No, by Allah, no! I will never do that unless (you promise me that) I will live with you in Paradise". Musa (AS) did not like what she said. However, he was told in a revelation that he should promise her what she wanted and he accepted her demand.
The old woman took them to a small pond and said to them, "Take out this water!" When the water was pumped out, she said, "Dig here!" When they had dug out the earth, they found the bones of Yusuf (AS) inside. Then they continued their exile with the bones of Yusuf with them. The path was clear to them shining like day-light. [Reported by Hakim in Mustadrak. Similar narration in Tabarani's Awsat and Ibn Hibban]
There are some lessons to be drawn from the story in this Hadith.
And whoever obeys Allah and the Messenger, these are with those upon whom Allah has bestowed favors from among the prophets and the truthful and the martyrs and the good, and a goodly company are they! [Al-Quran, 4:69]
With all the promises in Paradise, which is the most valuable? Perhaps this story can give a hint; companionship with the best of peoples and, even more valuable, the following verse,
وُجُوهٌ يَوْمَئِذٍ نَاضِرَةٌ
[75:22] (Some) faces on that day shall be bright,
إِلَىٰ رَبِّهَا نَاظِرَةٌ
[75:23] Looking to their Lord.
