Arabic (Original)
حَدَّثَنَا إِسْمَاعِيلُ عَنْ يُونُسَ عَنِ الْحَسَنِ أَنَّ النُّعْمَانَ بْنَ بَشِيرٍ كَتَبَ إِلَى قَيْسِ بْنِ الْهَيْثَمِ إِنَّكُمْ إِخْوَانُنَا وَأَشِقَّاؤُنَا وَإِنَّا شَهِدْنَا وَلَمْ تَشْهَدُوا وَسَمِعْنَا وَلَمْ تَسْمَعُوا وَإِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَقُولُ إِنَّ بَيْنَ يَدَيْ السَّاعَةِ فِتَنًا كَأَنَّهَا قِطَعُ اللَّيْلِ الْمُظْلِمِ يُصْبِحُ الرَّجُلُ فِيهَا مُؤْمِنًا وَيُمْسِي كَافِرًا وَيَبِيعُ فِيهَا أَقْوَامٌ خَلَاقَهُمْ بِعَرَضٍ مِنْ الدُّنْيَا.
English Translation
Isma'il told us, from Yunus, from al-Hasan, that al-Nu'man b. Bashir wrote to Qays b. al-Haytham: "You are our brothers and kin, but we witnessed what you did not witness, and we heard what you did not hear. The Messenger of Allah, peace and blessings be upon him, used to say: 'Before the Hour there will be tribulations like pieces of dark night; a man will be a believer in the morning and a disbeliever by evening, and people will sell their share of faith for a small worldly gain.'"
