Muwatta Imam Malik Book of The Qur'an, Hadith 46
Yahya related to me from Malik that al-Ala ibn Abd ar-Rahman said, "We visited Anas ibn Malik after dhuhr and he stood up and prayed asr. When he had finished his prayer, we mentioned doing prayers early in their time, or he mentioned it, and he said that he had heard the Messenger of Allah ﷺ say, the prayer of the hypocrites, the prayer of the hypocrites, the prayer of the hypocrites is that one of them sits until the sun becomes yellow and is between the horns of Shaytan, or on the horn of Shaytan, and then gets up and rattles off four rakas, hardly remembering Allah in them at all.' "
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ، قَالَ دَخَلْنَا عَلَى أَنَسِ بْنِ مَالِكٍ بَعْدَ الظُّهْرِ فَقَامَ يُصَلِّي الْعَصْرَ فَلَمَّا فَرَغَ مِنْ صَلاَتِهِ ذَكَرْنَا تَعْجِيلَ الصَّلاَةِ أَوْ ذَكَرَهَا فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ " تِلْكَ صَلاَةُ الْمُنَافِقِينَ تِلْكَ صَلاَةُ الْمُنَافِقِينَ تِلْكَ صَلاَةُ الْمُنَافِقِينَ يَجْلِسُ أَحَدُهُمْ حَتَّى إِذَا اصْفَرَّتِ الشَّمْسُ وَكَانَتْ بَيْنَ قَرْنَىِ الشَّيْطَانِ - أَوْ عَلَى قَرْنِ الشَّيْطَانِ - قَامَ فَنَقَرَ أَرْبَعًا لاَ يَذْكُرُ اللَّهَ فِيهَا إِلاَّ قَلِيلاً " .
