Musnad Ahmad Hadith 14101

It is narrated from Anas (may Allah be pleased with him) that there was a man who was very heavy and could not come repeatedly to pray with the Prophet (ﷺ). He said to the Prophet (ﷺ) that he did not have the strength to come again and again to pray with him, and requested that if the Prophet (ﷺ) would come to his house one day and pray at a certain place, then he would perform his prayers there. So, he once arranged an invitation and called the Prophet (ﷺ), and sprinkled water on a corner of a mat. The Prophet (ﷺ) prayed two rak‘ahs there. A man from the family of Jarud, upon hearing this, asked Anas (may Allah be pleased with him) whether the Prophet (ﷺ) used to pray the Duha prayer. He replied that he had only seen the Prophet (ﷺ) perform that prayer on that day.
