A man said to the Prophet ﷺ "Tell me of such a deed as will make me enter Paradise." The people said, "What is the matter with him? What is the matter with him?" The Prophet ﷺ said, "He has something to ask. (What he needs greatly) The Prophet ﷺ said: (In order to enter Paradise) you should worship Allah and do not ascribe any partners to Him, offer prayer perfectly, pay the Zakat and keep good relations with your Kith and kin." (See Hadith No. 12, Vol 8).  

لِلنَّبِيِّ ﷺ أَخْبِرْنِي بِعَمَلٍ يُدْخِلُنِي الْجَنَّةَ قَالَ مَا لَهُ مَا لَهُ وَقَالَ النَّبِيُّ ﷺ أَرَبٌ مَالَهُ تَعْبُدُ اللَّهَ وَلاَ تُشْرِكُ بِهِ شَيْئًا وَتُقِيمُ الصَّلاَةَ وَتُؤْتِي الزَّكَاةَ وَتَصِلُ الرَّحِمَ وَقَالَ بَهْزٌ حَدَّثَنَا شُعْبَةُ حَدَّثَنَا مُحَمَّدُ بْنُ عُثْمَانَ وَأَبُوهُ عُثْمَانُ بْنُ عَبْدِ اللَّهِ أَنَّهُمَا سَمِعَا مُوسَى بْنَ طَلْحَةَ عَنْ أَبِي أَيُّوبَ بِهَذَا قَالَ أَبُو عَبْدِ اللَّهِ أَخْشَى أَنْ يَكُونَ مُحَمَّدٌ غَيْرَ مَحْفُوظٍ إِنَّمَا هُوَ عَمْرٌو
