2. Abu Ali al-Ash’ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from ‘Abd al-Rahman ibn al-Hajjaj who has said the following: “I once asked abu Ibrahim , about the case of a people for whom offering animals become very expensive, who are for al-Tamattu‘ (advantageous), in one company but not of the same family. They have come together; their way and camp is one, if they can slaughter one cow. He (the Imam) said, ‘I do not like it unless it is urgency.’”
