Sufyaan narrated to us from Abuz-Zubayr from [Muhammad] ibn al-Munkadir who said that he heard Jaabir ibn ‘Abdullaah(May Allah be pleased with him), say,
“The Messenger of Allah (May Allah’s peace and blessings be on him) was never asked for anything to which he said, ‘no.”‘
(Musnad Ahmad, Vol. 3, p. 307. The isnaad of this b_adeeth is saheeh according to the conditions set by Muslim.)
