It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Military expeditions (jihad) are of two kinds: as for the one who seeks the pleasure of Allah, obeys the imam, spends his finest wealth, treats his companion gently and avoids corruption, his sleeping and his waking are all reward. But as for the one who fights out of pride, for show and for reputation, disobeys the imam and spreads corruption in the land, he will not even return breaking even (between reward and sin)." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that a man said: O Messenger of Allah, a man intends to wage jihad in the way of Allah, but he also seeks some of the goods of this world. The Messenger of Allah (peace and blessings be upon him) said: "There is no reward for him." The man asked the same question a second and a third time, and the Messenger of Allah (peace and blessings be upon him) said the same (each time): "There is no reward for him." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that he said: O Messenger of Allah, tell me about jihad and military expeditions. He (peace and blessings be upon him) said: "O Abdullah bin Amr, if you fight with patience and seeking reward, Allah will raise you (on the Day of Resurrection) as one who was patient and sought reward; and if you fight for show and pride, Allah will raise you as one who showed off and took pride. O Abdullah bin Amr, in whatever state you fight or are killed, Allah will raise you in that same state." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it. This Muhammad bin Abi al-Waddah is Abu Sa'id Muhammad bin Muslim bin Abi al-Waddah, a trustworthy (thiqah) and reliable (ma'mun) narrator.

It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "May Allah Almighty have mercy on the one who guards the guards." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him). Sa'sa'ah bin Mu'awiyah said: I asked Sayyiduna Abu Dharr (may Allah be pleased with him): What is your wealth? He said: My wealth is my deeds, my wealth is my deeds. I said: Narrate a hadith to me. He said: Yes. The Prophet (peace and blessings be upon him) said: "There is no servant who spends a pair (two items) from every kind of his wealth in the way of Allah, except that the gatekeepers of Paradise come forward to receive him, each of them calling him to himself." I asked: How is that? He said: "If they are slaves, then two; if they are camels, then two; and if they are cows, then two." This hadith has a sahih (authentic) chain of narration. Sa'sa'ah bin Mu'awiyah is among the illustrious men of the Arabs, and the companions of al-Hasan al-Basri narrated it from him.

I heard Abu al-Abbas Muhammad bin Ya'qub say: I heard Abbas bin Muhammad al-Duri say: I heard Yahya bin Ma'in say: Sa'sa'ah bin Mu'awiyah was the companion of Sayyiduna Abu Dharr (may Allah be pleased with him), and he is the brother of Jazi bin Mu'awiyah.

I heard Abu Hafs Umar bin Ja'far al-Basri, the hafiz, say more than once: The people of Basrah have no chapter (of knowledge) better than the chains of the hadith of Imam al-Hasan from Sa'sa'ah. Imam al-Hakim said: So I searched for the chains of this hadith and gathered them. Then, when we met a second time in Baghdad, I mentioned it to him, and he gave me valuable information about it that I did not have before. Then one day I told this story to al-Hakim Abu Ahmad, the hafiz (may Allah have mercy on him), and discussed it with him, and he asked me: Who other than Sa'sa'ah narrated this hadith from Sayyiduna Abu Dharr (may Allah be pleased with him)? And I could not remember.

It is narrated from Sulaym bin Amir that a man asked Sayyiduna Abu Dharr (may Allah be pleased with him): "What is your wealth?" He said: "My wealth is my deeds." Then he narrated the long hadith. The two Shaykhs (Bukhari and Muslim) recorded, through the narration of al-Zuhri, the hadith: "Whoever spends a pair from his wealth in the way of Allah," but its wording differs from the narration of Sa'sa'ah.

It is narrated from Sayyiduna Khuraym bin Fatik al-Asadi (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever spends something in the way of Allah, seven hundredfold (reward) is written for him." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it. Imam Muslim used al-Rukayn bin al-Rabi' as evidence; he is a Kufan narrator with few hadith, and Yusayr bin Umaylah is his paternal uncle.

It is narrated from Sayyiduna Khuraym bin Fatik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "People are of four kinds, and deeds are of six kinds: two deeds make (something) obligatory, one deed is repaid with its equal, one tenfold, and one seven hundredfold. Whoever dies in a state of disbelief, the Fire becomes obligatory for him, and whoever dies in a state of faith, Paradise becomes obligatory for him. When a servant commits an evil deed, he is repaid only with its equal; when a servant intends a good deed, the reward of ten good deeds is written for him; and when a servant spends something in the way of Allah, it is multiplied for him seven hundredfold. And people are of four kinds: one who is given abundance in this world and also in the Hereafter; one who is given abundance in this world but has hardship in the Hereafter; one who is given hardship in this world but abundance in the Hereafter; and one who is wretched in (both) this world and the Hereafter."
