Hazrat Abu Harira (Ra:) says, "One day we presented for serving Hazrat Rosulullah (SM:) and we sat down around him. Hazrat Abu Bakar (Ra:) and Omar (Ra:) also presented with us. At that time Hazrat Rosulullah (SM:) went away from us. After that, we became worried due to his delaying thinking that leaving us whether he felt in danger or not and we started to look for him. I went out for searching him before all. I reached in garden of Anser’s Bonu Nazzar’s lineage. The garden was surrounded by four walls, I came here and wandered around in order to search the way to go inside. But I did not get any way. Suddenly I saw a little drain which is flowing from a out side deep whole and enter in to the garden. I illustrated myself and entered into the garden through this drain and reached in front of Hazrat Rosulullah (SM:). Seeing me Hazrat Rosulullah (SM:) asked, "Abu Horira?" I Answered, "yes, ya Rasulullah (sm:)"! He asked again, "how you came here?" I answered, "ya Rasulullah (sm:)! you were among us, suddenly came out. When we saw that you were making late, then uncertainty attacked us that, whether you fall in danger or not. For this we worried and went out for searching you. I went out before all worriedly. At last I reached in this garden. When I did not get any way to enter here then I came here through the drain like a fox. Another people also behind me. At that time Hazrat Rosulullah (SM:) gave his shoes in my hand and told, 'take my shoes and leave this garden and give the news of heaven to whom who witnesses 'LA-ELAHA ELLALLAH' heartly. Abu Hurira (Ra:) told, 'I left the place and go went infront. With whom I met first, he was Hazrat Omar (Ra:). He asked me, 'Abu Hurira! what is the wonder of the shoes in your hand?'
