عَنْ زَيْدِ بْنِ أَرْقَمَ رَضِيَ اللَّهُ عَنْهُ قَالَ: خَرَجَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَلَى أَهْلِ قُبَاءٍ وَهُمْ يُصَلُّونَ الضُّحَى، فَقَالَ: ((صَلَاةُ الْأَوَّابِينَ إِذَا رَمِضَتِ الْفِصَالُ مِنَ الضُّحَى))
It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) came to the people of Quba and they were performing the Duha (forenoon) prayer. The Prophet (peace and blessings be upon him) said: The prayer of the Awabeen is at the time when the hooves of the young camels are scorched by the heat of the forenoon.
