[Good For Here & Hereafter]
"When intending to do something good, do not delay it until tomorrow. When involved in something to do with the hereafter, keep yourself involved as long as you can. When involved in some worldly matter, put your mind to it-so as to get it done. And if you are praying and Satan whispers, ‘You are showing off,’ then make your prayer even longer."
[Ibn Al-Mubârak in Al-Zuhd wa Al-Rqâ’iq Vol.1 p126]
