Have you said the afternoon prayer? We said to him: It is just a few minutes before that we finished the noon prayer. He said: Offer the afternoon prayer. So we stood up and said our prayer. And when we completed it, he said: I have heard the Messenger of Allah ﷺ saying: This is how the hypocrite prays: he sits watching the sun, and when it is between the horns of devil, he rises and strikes the ground four times (in haste) mentioning Allah a little during it. (Using translation from Muslim 622)
صَلَّيْتُمُ الْعَصْرَ؟ قُلْنَا لَا إِنَّمَا انْصَرَفْنَا السَّاعَةَ مِنَ الظُّهْرِ قَالَ فَصَلُّوا الْعَصْرَ قَالَ فَقُمْنَا فَصَلَّيْنَا فَلَمَّا انْصَرَفْنَا قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «تِلْكَ صَلَاةُ الْمُنَافِقِ جَلَسَ يَرْقُبُ الْعَصْرَ حَتَّى إِذَا كَانَتْ بَيْنَ قَرْنَيِ الشَّيْطَانِ قَامَ فَنَقَرَ أَرْبَعًا لَا يَذْكُرُ اللهَ فِيهَا إِلَّا قَلِيلًا»
