Narrated Ibn `Abbas (RAA):

It is from the Sunnah of the Prophet (ﷺ) for the man to pray only one prayer with each Tayammum, and then perform Tayammum for the next prayer. [Reported by Ad-Daraqutni but with a very weak chain of narrators]

وَعَنِ ابْنِ عَبَّاسٍ رَضِيَ اَللَّهُ عَنْهُمَا قَالَ: { مِنْ اَلسُّنَّةِ أَنْ لَا يُصَلِّيَ اَلرَّجُلُ بِالتَّيَمُّمِ إِلَّا صَلَاةً وَاحِدَةً, ثُمَّ يَتَيَمَّمُ لِلصَّلَاةِ اَلْأُخْرَى } رَوَاهُ اَلدَّارَقُطْنِيُّ بِإِسْنَادٍ ضَعِيفٍ جِدًّ ا [1]‏ .‏
