To offer two Rak‘a before the Zuhr prayer

Narrated Ibn 'Umar:

I remember ten Rakat of Nawafil from the Prophet, two Rakat before the Zuhr prayer and two after it;
two Rakat after Maghrib prayer in his house, and two Rakat after 'Isha' prayer in his house, and two Rakat before the Fajr prayer and at that time nobody would enter the house of the Prophet Hafsa told me that the Prophet used to offer two Rakat after the call maker had made the Adhan and the day had dawned.

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ حَفِظْتُ مِنَ النَّبِيِّ ﷺ عَشْرَ رَكَعَاتٍ رَكْعَتَيْنِ قَبْلَ الظُّهْرِ، وَرَكْعَتَيْنِ بَعْدَهَا، وَرَكْعَتَيْنِ بَعْدَ الْمَغْرِبِ فِي بَيْتِهِ، وَرَكْعَتَيْنِ بَعْدَ الْعِشَاءِ فِي بَيْتِهِ، وَرَكْعَتَيْنِ قَبْلَ صَلاَةِ الصُّبْحِ، وَكَانَتْ سَاعَةً لاَ يُدْخَلُ عَلَى النَّبِيِّ ﷺ فِيهَا. حَدَّثَتْنِي حَفْصَةُ، أَنَّهُ كَانَ إِذَا أَذَّنَ الْمُؤَذِّنُ وَطَلَعَ الْفَجْرُ صَلَّى رَكْعَتَيْنِ.

Narrated by Anas bin Sirin

I heard Anas bin Malik al-Ansari saying, "An Ansari man, who was very fat, said to the Prophet, 'I am unable to present myself for the prayer with you.' He prepared a meal for the Prophet and invited him to his house. He washed one side of a mat with water and the Prophet offered two Rakat on it." So and so, the son of so and so, the son of Al-Jarud asked Anas, "Did the Prophet use to offer the Duha prayer?" Anas replied, "I never saw him praying (the Duha prayer) except on that day."

حَدَّثَنَا عَلِيُّ بْنُ الْجَعْدِ، أَخْبَرَنَا شُعْبَةُ، عَنْ أَنَسِ بْنِ سِيرِينَ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ الأَنْصَارِيَّ، قَالَ قَالَ رَجُلٌ مِنَ الأَنْصَارِ ـ وَكَانَ ضَخْمًا ـ لِلنَّبِيِّ ﷺ إِنِّي لاَ أَسْتَطِيعُ الصَّلاَةَ مَعَكَ. فَصَنَعَ لِلنَّبِيِّ ﷺ طَعَامًا، فَدَعَاهُ إِلَى بَيْتِهِ، وَنَضَحَ لَهُ طَرَفَ حَصِيرٍ بِمَاءٍ فَصَلَّى عَلَيْهِ رَكْعَتَيْنِ. وَقَالَ فُلاَنُ بْنُ فُلاَنِ بْنِ جَارُودٍ لأَنَسٍ ـ رضى الله عنه ـ أَكَانَ النَّبِيُّ ﷺ يُصَلِّي الضُّحَى فَقَالَ مَا رَأَيْتُهُ صَلَّى غَيْرَ ذَلِكَ الْيَوْمِ.
