English Translation of Hadith
Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said, "He who spends a pair in the way of Allah will be called from the gates of Jannah: `O slave of Allah! This gate is better for you’ and one who is constant in Salat (prayer), will be called from the Gate of Salat; and whoever is eager in fighting in the Cause of Allah, will be called from the Gate of Jihad; and who is regular in observing Saum will be called from Ar-Raiyan Gate. The one who is generous in charity will be called from the Gate of Charity.” Abu Bakr (May Allah be pleased with him) said: "O Messenger of Allah [SAWW](PBUH)! May my mother and father be sacrificed for you! Those who are called from these gates will stand in need of nothing. Will anybody be called from all of those gates?” He replied, "Yes, and I hope that you will be one of them.”
[Al-Bukhari Book 03, Chapter 31, Hadith # 121].
Lesson : "Pair” means two; in other channels of transmission, it has been explained thus: "They asked him, `Pair of what?’ He [SAWW](PBUH) said, `A pair of horses, cows or camels’.” "Pair” in this Hadith, however, can be all-inclusive; i.e., fasting two days or performing two prayers, etc. This Hadith also mentions special distinction of Abu Bakr As-Siddiq (May Allah be pleased with him) and the esteem in which he was held by the Prophet [SAWW](PBUH). It also transpires from this Hadith that one can praise such a person right on his face about whom one does not fear that it will make him proud. This Hadith has also an inducement for giving in Sadaqah two instead of a single item.
