Whenhe came to us, he asked us, 'Shall I pray with you?' It was not the timeof an obligatory prayer." One of those listening to the person relating thisasked, "Where did he put in Anas in relation to him?" The reply was, "Heput him to his right." The report from Anas continues, "Then he prayed withus and made supplication for us, the people of the house, that we would havethe best of the blessings of this world and the Next. My mother said, 'Messengerof Allah, make supplication to Allah for your little servant,' and he askedAllah to grant me every blessing. At the end of his supplication, he said,'O Allah, grant him a lot of money and many children and bless him!'"
