What is Sufism in Islam, and how SEYIDINA ABU BAKR PERFORM SUFI.

__Surah Fatir, Verse 31:
وَالَّذِي أَوْحَيْنَا إِلَيْكَ مِنَ الْكِتَابِ هُوَ الْحَقُّ مُصَدِّقًا لِّمَا بَيْنَ يَدَيْهِ إِنَّ اللَّهَ بِعِبَادِهِ لَخَبِيرٌ بَصِيرٌ

And that which We have revealed to you of the Book, that is the truth verifying that which is before it; most surely with respect to His servants Allah is Aware, Seeing.
Surah Fatir, Verse 32:
ثُمَّ أَوْرَثْنَا الْكِتَابَ الَّذِينَ اصْطَفَيْنَا مِنْ عِبَادِنَا فَمِنْهُمْ ظَالِمٌ لِّنَفْسِهِ وَمِنْهُم مُّقْتَصِدٌ وَمِنْهُمْ سَابِقٌ بِالْخَيْرَاتِ بِإِذْنِ اللَّهِ ذَٰلِكَ هُوَ الْفَضْلُ الْكَبِيرُ

Then We gave the Book for an inheritance to those whom We chose from among Our servants; but of them is he who makes his soul to suffer a loss, and of them is he who takes a middle course, and of them is he who is foremost in deeds of goodness by Allah's permission; this is the great excellence.
Surah Fatir, Verse 33:
جَنَّاتُ عَدْنٍ يَدْخُلُونَهَا يُحَلَّوْنَ فِيهَا مِنْ أَسَاوِرَ مِن ذَهَبٍ وَلُؤْلُؤًا وَلِبَاسُهُمْ فِيهَا حَرِيرٌ

Gardens of perpetuity, they shall enter therein; they shall be made to wear therein bracelets of gold and pearls, and their dress therein shall be silk.
Surah Fatir, Verse 34:
وَقَالُوا الْحَمْدُ لِلَّهِ الَّذِي أَذْهَبَ عَنَّا الْحَزَنَ إِنَّ رَبَّنَا لَغَفُورٌ شَكُورٌ

And they shall say: (All) praise is due to Allah, Who has made grief to depart from us; most surely our Lord is Forgiving, Multiplier of rewards,
Surah Fatir, Verse 35:
الَّذِي أَحَلَّنَا دَارَ الْمُقَامَةِ مِن فَضْلِهِ لَا يَمَسُّنَا فِيهَا نَصَبٌ وَلَا يَمَسُّنَا فِيهَا لُغُوبٌ

Who has made us alight in a house abiding for ever out of His grace; toil shall not touch us therein, nor shall fatigue therein afflict us.
(English - Shakir)
