It is narrated from Hazrat Jarir (may Allah be pleased with him) that at the time of accepting Islam, he took the pledge from the Holy Prophet (peace and blessings be upon him) on the condition that he would not associate anyone with Allah, would perform the obligatory prayers, pay the obligatory zakat, wish well for every Muslim, and express disavowal from the disbeliever.
