Narrated Said bin 'Abdur Rahman bin Abza:

(on the authority of his father who said) 'Ammar said so (the above Statement). And Shu'ba stroked lightly the earth with his hands and brought them close to his mouth (blew off the dust) and passed them over his face and then the backs of his hands. 'Ammar said, "Ablution (meaning Tayammum here) is sufficient for a Muslim if water is not available."

حَدَّثَنَا حَجَّاجٌ، قَالَ أَخْبَرَنَا شُعْبَةُ، أَخْبَرَنِي الْحَكَمُ، عَنْ ذَرٍّ، عَنْ سَعِيدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى، عَنْ أَبِيهِ، قَالَ عَمَّارٌ بِهَذَا، وَضَرَبَ شُعْبَةُ بِيَدَيْهِ الأَرْضَ، ثُمَّ أَدْنَاهُمَا مِنْ فِيهِ، ثُمَّ مَسَحَ وَجْهَهُ وَكَفَّيْهِ. وَقَالَ النَّضْرُ أَخْبَرَنَا شُعْبَةُ عَنِ الْحَكَمِ قَالَ سَمِعْتُ ذَرًّا يَقُولُ عَنِ ابْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى قَالَ الْحَكَمُ وَقَدْ سَمِعْتُهُ مِنِ ابْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِيهِ قَالَ قَالَ عَمَّارٌ.
