Yaqīn (يقين, الْيَقِينُ)
Conviction, certainty
وَ قَالَ ع الْإِيمَانُ فِي الْقَلْبِ وَ الْيَقِينُ خَطَرَاتٌ
And he-asws (6th Imam) said: ‘The Eman is in the heart, and the certainty are thoughts’.[1]
قَالَ قُلْتُ فَأَيُّ شَيْءٍ الْيَقِينُ
He (the narrator) said, ‘I said, ‘So which thing is the certainty?’
قَالَ التَّوَكُّلُ عَلَى اللَّهِ وَ التَّسْلِيمُ لِلَّهِ وَ الرِّضَا بِقَضَاءِ اللَّهِ وَ التَّفْوِيضُ إِلَى اللَّهِ
He-asws said: ‘The reliance upon Allah-azwj, and the submission to Allah-azwj, and the satisfaction with the Decree of Allah-azwj, and the delegating (the affairs) to Allah-azwj’.
قُلْتُ مَا تَفْسِيرُ ذَلِكَ
I said, ‘What is the interpretation of that?’
قَالَ هَكَذَا قَالَ أَبُو جَعْفَرٍ ع.
He-asws said: ‘Like that Abu Ja’far-asws had said’’.[2]
