[Machine] The Messenger of Allah ﷺ said, "Whoever combines two prayers without an excuse has opened a door from the gates of major sins." Hanash bin Qays Al-Rahbi, also known as Abu Ali from the people of Yemen, resided in Kufa and was trustworthy. And Al-Bukhari referred to Ikrimah as evidence, and this hadith is a basis for prohibition against combining prayers without an excuse, and they did not exclude it. This was mentioned in the context of validating the narration of Hakeem regarding Hanash, but they weakened it.  

قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ جَمَعَ بَيْنَ الصَّلَاتَيْنِ مِنْ غَيْرِ عُذْرٍ فَقَدْ أَتَى بَابًا مِنْ أَبْوَابِ الْكَبَائِرِ» حَنَشُ بْنُ قَيْسٍ الرَّحَبِيُّ يُقَالُ لَهُ أَبُو عَلِيٍّ مِنْ أَهْلِ الْيَمَنِ سَكَنَ الْكُوفَةَ ثِقَةٌ «وَقَدِ احْتَجَّ الْبُخَارِيُّ بِعِكْرِمَةَ وَهَذَا الْحَدِيثُ قَاعِدَةٌ فِي الزَّجْرِ عَنِ الْجَمْعِ بِلَا عُذْرٍ وَلَمْ يُخَرِّجَاهُ» معقبا على توثيق الحاكم لحنش بل ضعفوه
