قَالَ الْحَارِثُ بْنُ مِسْكِينٍ قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، عَنِ ابْنِ وَهْبٍ، قَالَ أَخْبَرَنِي أَبُو هَانِئٍ، عَنْ عَمْرِو بْنِ مَالِكٍ الْجَنْبِيِّ، أَنَّهُ سَمِعَ فَضَالَةَ بْنَ عُبَيْدٍ، يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏ أَنَا زَعِيمٌ - وَالزَّعِيمُ الْحَمِيلُ - لِمَنْ آمَنَ بِي وَأَسْلَمَ وَهَاجَرَ بِبَيْتٍ فِي رَبَضِ الْجَنَّةِ وَبِبَيْتٍ فِي وَسَطِ الْجَنَّةِ وَأَنَا زَعِيمٌ لِمَنْ آمَنَ بِي وَأَسْلَمَ وَجَاهَدَ فِي سَبِيلِ اللَّهِ بِبَيْتٍ فِي رَبَضِ الْجَنَّةِ وَبِبَيْتٍ فِي وَسَطِ الْجَنَّةِ وَبِبَيْتٍ فِي أَعْلَى غُرَفِ الْجَنَّةِ مَنْ فَعَلَ ذَلِكَ فَلَمْ يَدَعْ لِلْخَيْرِ مَطْلَبًا وَلاَ مِنَ الشَّرِّ مَهْرَبًا يَمُوتُ حَيْثُ شَاءَ أَنْ يَمُوتَ ‏"‏ ‏.‏

It was narrated from 'Amr bin Malik Al-Janbi that he heard Fadalah bin 'Ubaid say: "I heard the Messenger of Allah (PBUH) say: 'I am a Za'im - and the Za'im is the guarantor - for the one who believes in me and accepts Islam, and emigrates: A house on the outskirts of Paradise and a house in the middle of Paradise. And I am a guarantor, for the one who believes in me and accepts Islam, and strives in the cause of Allah: A house on the outskirts of Paradise and a house in the middle of Paradise and a house in the highest chambers of Paradise. Whoever does that and seeks goodness wherever it is, and avoids evil wherever it is, may die wherever he wants to die.'" Translation Not Available
