Sahih Muslim , Book 4, Hadith 1301 (USC-MSA) ⓘ

'Ala' b. 'Abd al-Rahman reported that they came to the house of Anas b. Malik in Basra after saying the noon prayer. His (Anas) house was situated by the side of the mosque. As revisited him he (Anas) said: 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 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.

وَحَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَمُحَمَّدُ بْنُ الصَّبَّاحِ، وَقُتَيْبَةُ، وَابْنُ، حُجْرٍ قَالُوا حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ، أَنَّهُ دَخَلَ عَلَى أَنَسِ بْنِ مَالِكٍ فِي دَارِهِ بِالْبَصْرَةِ حِينَ انْصَرَفَ مِنَ الظُّهْرِ وَدَارُهُ بِجَنْبِ الْمَسْجِدِ فَلَمَّا دَخَلْنَا عَلَيْهِ قَالَ أَصَلَّيْتُمُ الْعَصْرَ فَقُلْنَا لَهُ إِنَّمَا انْصَرَفْنَا السَّاعَةَ مِنَ الظُّهْرِ ‏.‏ قَالَ فَصَلُّوا الْعَصْرَ ‏.‏ فَقُمْنَا فَصَلَّيْنَا فَلَمَّا انْصَرَفْنَا قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ تِلْكَ صَلاَةُ الْمُنَافِقِ يَجْلِسُ يَرْقُبُ الشَّمْسَ حَتَّى إِذَا كَانَتْ بَيْنَ قَرْنَىِ الشَّيْطَانِ قَامَ فَنَقَرَهَا أَرْبَعًا لاَ يَذْكُرُ اللَّهَ فِيهَا إِلاَّ قَلِيلاً ‏" ‏ ‏.‏
