Advice of Hasan al Basr to Umar bin Abd al Aziz

It is reported that ‘Umar bin ‘Abd Al-‘Aziz once wrote to Al-Hasan Al- Basri to get a brief exhortation from him, so Al-Hasan wrote back ,

“The dunya distracts and preoccupies the heart and body, but
al-zuhd (asceticism, not giving importance to worldly things)
gives rest to the heart and body. Verily, Allah will ask us about
the halal things we enjoyed, so what about the haram!”
