Abu Ma'mar said, "A man began to praise one of the amirs. Al-Miqdad began to throw dirt in his face and said, 'The Messenger of Allah, may Allah bless him and grant him peace, commanded us to throw dust into the faces of those who praise people.'"  

عَنْ أَبِي مَعْمَرٍ قَالَ قَامَ رَجُلٌ يُثْنِي عَلَى أَمِيرٍ مِنَ الأُمَرَاءِ فَجَعَلَ الْمِقْدَادُ يَحْثِي فِي وَجْهِهِ التُّرَابَ وَقَالَ أَمَرَنَا رَسُولُ اللهِ ﷺ أَنْ نَحْثِيَ فِي وُجُوهِ الْمَدَّاحِينَ التُّرَابَ  

'Ata' ibn Abi Rabah reported that a man was praising another man in the presence of Ibn 'Umar. Ibn 'Umar began to throw dust towards his mouth. He said, "The Messenger of Allah, may Allah bless him and grant him peace, said, 'When you see those who praise people, throw dust in their faces.'"  

قَالَ رَسُولُ اللهِ ﷺ إِذَا رَأَيْتُمُ الْمَدَّاحِينَ فَاحْثُوا فِي وُجُوهِهِمُ التُّرَابَ  

Raja' said. "One day Mihjan and I went to the mosque of the people of Basra. Burayda al-Aslami was sitting there by one of the mosque doors. Inside the mosque there was a man called Sabka who used to make the prayers long. We came to the mosque door which had a fringed woollen cloth over it. Now Burayda was someone who made jokes. He said, 'Mihjan, don't you pray as Sabka prays?' Mihjan did not answer and went back. Mihjan said, 'The Messenger of Allah, may Allah bless him and grant him peace, once took me by the hand and we went together to the top of Uhud. He looked down on Madina and said, "Woe to a town whose people will abandon it when it becomes very prosperous. Then the Dajjal will come to it and find two angels at each of its gates, so he will not enter it." Then he went down until we reached the mosque and the Messenger of Allah, may Allah bless him and grant him peace, saw a man praying, prostrating and bowing. The Messenger of Allah, may Allah bless him and grant him peace, asked me, "Who is this?" and I began to praise him, saying, "Messenger of Allah, this is so-and-so and so-and-so." "Stop!" he said, "Do not let him hear or you will destroy him."'"
