Earn ones living

Imam Jafar al-Sadiq (‘a) was busy working in his garden, wearing working clothes with spade in hand, when one of his friends, Abu Umro Shaibani arrived. Seeing him drenched in perspiration because of the heat and labour, he thought there was need of a labourer, so the Imam (‘a) had opted to work himself.
He stepped forward and said, ‘Let me help you finish this work.’
The Imam (‘a) said, ‘No. I like working on the farm with my own hands. It is necessary for man to face the heat of the sun and feel the exhaustion of earning ones own living.’
