With established truth one does not live in doubts
Al-Kāfi|Volume 8|Book 1|Chapter 333
عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ بَعْضِ أَصْحَابِنَا عَنْ مُحَمَّدِ بْنِ الْهَيْثَمِ عَنْ زَيْدٍ أَبِي الْحَسَنِ قَالَ سَمِعْتُ أَبَا عَبْدِ اللَّهِ (عليه السلام) يَقُولُ مَنْ كَانَتْ لَهُ حَقِيقَةٌ ثَابِتَةٌ لَمْ يَقُمْ عَلَى شُبْهَةٍ هَامِدَةٍ حَتَّى يَعْلَمَ مُنْتَهَى الْغَايَةِ وَ يَطْلُبَ الْحَادِثَ مِنَ النَّاطِقِ عَنِ الْوَارِثِ وَ بِأَيِّ شَيْءٍ جَهِلْتُمْ مَا أَنْكَرْتُمْ وَ بِأَيِّ شَيْءٍ عَرَفْتُمْ مَا أَبْصَرْتُمْ إِنْ كُنْتُمْ مُؤْمِنِينَ.
333. A number of our companions, from Ahmad Bin Muhammad Bin Khalid, from one of our companions, from Muhammad Bin Al-Haysam, from Zayd Abu Al-Hassan who said: I heard Abu Abdullah عليه الصلاة والسلام saying: ‘The one for whom the facts are established will never stand upon lifeless doubts. He will not stop until he comes to know the ultimate goal, and seeks the (explanation for) the newly emerging issues from the one who speaks from the inheritors عليه الصلاة والسلام, and for which thing you are ignorant of, what you have denied, and by which thing you have come to recognise what you have visualised, if you are Believers’.
