Description: Imam Ali (a.s.) said to a man soliciting advice from him, 'Do not be of those who hope for [bliss in] the life of the Hereafter without action, and delay repentance by having high expectations [of being forgiven], and who utter words like the ascetics with regard to this world, though in practice they behave like those who covet it.’
الإمامُ عليٌّ (عَلَيهِ الّسَلامُ) ـ لِرَجُلٍ سَألَهُ أن يَعِظَهُ ـ: لا تَكُن مِمَّن يَرجُو الآخِرَةَ بغَيرِ العَمَلِ ويُرَجِّي التَّوبَةَ بطُولِ الأمَلِ ، يَقولُ في الدنيا بقَولِ الزاهِدِينَ ويَعمَلُ فيها بعَمَلِ الراغِبينَ.

Description: Someone came to Imam al-Sadiq (a.s.) and told him that there was a group of people who were disobeying Allah, but at the same time they were saying that they hoped [in His mercy], and remained thus until death overtook them. Imam (a.s.) said, ‘These are people who swing back and forth between their desires. They are lying and are not really hopeful, for the one who hopes for something seeks it, and the one who fears something flees from it.’

Description: Imam Ali (a.s.) said, 'Place all your hope in Allah, glory be to Him, and do not hope from anyone else apart from Him, for no sooner does anyone place his hope in anyone other than Allah than he fails.’
