Sunan an-Nasa'i 3185
It was narrated that Sa'sa'ah bin Mu'awiyah said:
"I met Abu Dharr and said: 'Tell me a Hadith.' He said. Yes, the Messenger of Allah (ﷺ) said: There is no Muslim worshiper who spends from each type of his wealth on a pair (of things) in the cause of Allah, but the keepers of Paradise will welcome him, all of them calling him to what they have (of reward).' I said: "How is that?" He said: "If it is camels, he gives two, and if it is cows, he gives two.'"
أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، قَالَ حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ، عَنْ يُونُسَ، عَنِ الْحَسَنِ، عَنْ صَعْصَعَةَ بْنِ مُعَاوِيَةَ، قَالَ لَقِيتُ أَبَا ذَرٍّ قَالَ قُلْتُ حَدِّثْنِي ‏.‏ قَالَ نَعَمْ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَا مِنْ عَبْدٍ مُسْلِمٍ يُنْفِقُ مِنْ كُلِّ مَالٍ لَهُ زَوْجَيْنِ فِي سَبِيلِ اللَّهِ إِلاَّ اسْتَقْبَلَتْهُ حَجَبَةُ الْجَنَّةِ كُلُّهُمْ يَدْعُوهُ إِلَى مَا عِنْدَهُ ‏"‏ ‏.‏ قُلْتُ وَكَيْفَ ذَلِكَ قَالَ ‏"‏ إِنْ كَانَتْ إِبِلاً فَبَعِيرَيْنِ وَإِنْ كَانَتْ بَقَرًا فَبَقَرَتَيْنِ ‏"‏ ‏.‏
