The Holy Prophet (peace be upon him and his holy progeny) once owed a few dinars to a Jew. One day, the Jew sought his money from him (peace be upon him and his holy progeny), whereupon he (peace be upon him and his holy progeny) said: Presently I do not have any money. The Jew said: I shall not leave you till you repay my money.
Hearing this, the Holy Prophet (peace be upon him and his holy progeny) said: If that is the case then I too shall sit by you here. He (peace be upon him and his holy progeny) sat down beside the Jew and continued to do so for such a long period that he recited his Dhuhr, Asr, Maghrib, Isha and the morning prayers of the next day, right there.
Observing the state of affairs, the companions of the Holy Prophet (peace be upon him and his holy progeny) began to threaten the Jew, but he (peace be upon him and his holy progeny) said to them: What is this that you are doing?
How can a Jew hold you a captive? They replied. Hearing this, the Holy Prophet (peace be upon him and his holy progeny) explained: God has not sent me as a Prophet in order that I permit those, who have established a religious covenant with me, to be oppressed.
Till sunrise of the next day he (peace be upon him and his holy progeny) continued to be seated there, whereupon the Jew, addressing the Holy Prophet (peace be upon him and his holy progeny), said: O Prophet of God! By God! It was not impertinence and audaciousness that prompted me to behave in the manner I did with you; rather, I desired to know whether the traits mentioned in the Torah about the Final Prophet, conformed with you or not?
This is because I have read in the Torah that Muhammad Ibn Abdullah would be born in Makkah, and subsequently emigrate to Medina; he would neither possess a bad temperament, nor would he be discourteous. He would not speak with a loud voice and would not be foul-mouthed and abusive.
I now bear witness to the Unity of God and to your Prophethood, and I place my entire wealth at your disposal for you to utilise in whatsoever manner God commands you to.( Daastaan-ha-e-Zindagi-e-Payaambar, p. 82; Bihar al-Anwar, v. 16, p. 16. )
