Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Ma’dan bin Abi Talha that Hazrat Umar bin Khattab said: You people eat two such plants which I consider foul. These are garlic and onion. In the blessed era of the Holy Prophet (peace and blessings be upon him), I used to see that if a person from whom their smell emanated, he would be taken by the hand and taken outside towards Baqi’. Even then, whoever among you is compelled to eat them should kill their (odor) by cooking them.
