If there is a Sutra between a praying person and the Imam

It was narrated that 'Aishah
said:

"The Messenger of Allah ﷺ had a mat which he would spread in the day and make into a small booth at night to pray in it. The people found out about that and they prayed when he prayed, with the mat in between him and them. He said: 'Do as much of good deeds as you can, for Allah does not get tired (of giving reward) until you get tired. And the most beloved of deeds to Allah are those that are continuous, even if they are few.' Then he stopped that prayer and did not return to it until Allah took him (in death), and if he started to do something he would persist in it."

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ عَجْلاَنَ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، قَالَتْ كَانَ لِرَسُولِ اللَّهِ ﷺ حَصِيرَةٌ يَبْسُطُهَا بِالنَّهَارِ وَيَحْتَجِرُهَا بِاللَّيْلِ فَيُصَلِّي فِيهَا فَفَطِنَ لَهُ النَّاسُ فَصَلَّوْا بِصَلاَتِهِ وَبَيْنَهُ وَبَيْنَهُمُ الْحَصِيرَةُ فَقَالَ " اكْلَفُوا مِنَ الْعَمَلِ مَا تُطِيقُونَ فَإِنَّ اللَّهَ عَزَّ وَجَلَّ لاَ يَمَلُّ حَتَّى تَمَلُّوا وَإِنَّ أَحَبَّ الأَعْمَالِ إِلَى اللَّهِ عَزَّ وَجَلَّ أَدْوَمُهُ وَإِنْ قَلَّ " . ثُمَّ تَرَكَ مُصَلاَّهُ ذَلِكَ فَمَا عَادَ لَهُ حَتَّى قَبَضَهُ اللَّهُ عَزَّ وَجَلَّ وَكَانَ إِذَا عَمِلَ عَمَلاً أَثْبَتَهُ .
