“The Messenger of Allah ﷺ came out to us when we were discussing Dajjal (False Christ) and said: ‘Shall I not tell you of that which I fear more for you than Dajjal?’ We said: ‘Yes.’ He said: ‘Hidden polytheism, when a man stands to pray and makes it look good because he sees a man looking at him.’”
خَرَجَ عَلَيْنَا رَسُولُ اللَّهِ ﷺ وَنَحْنُ نَتَذَاكَرُ الْمَسِيحَ الدَّجَّالَ فَقَالَ أَلاَ أُخْبِرُكُمْ بِمَا هُوَ أَخْوَفُ عَلَيْكُمْ عِنْدِي مِنَ الْمَسِيحِ الدَّجَّالِ قَالَ قُلْنَا بَلَى فَقَالَ الشِّرْكُ الْخَفِيُّ أَنْ يَقُومَ الرَّجُلُ يُصَلِّي فَيُزَيِّنُ صَلاَتَهُ لِمَا يَرَى مِنْ نَظَرِ رَجُلٍ
