Planting trees and other matters

Khallad bin al-Sa'ib reports from his father: The Prophet (peace and blessings be upon him) said: "Whoever plants a crop and a bird or any seeker of provision (a human, an animal or the like) eats something from it, that person receives (the reward of) charity."
Imam Ahmad and al-Tabarani in al-Mu'jam al-Kabir recorded it, and its chain is hasan (good).

Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: "Whoever plants a sapling (or tree), Allah Almighty records for him a reward in proportion to the fruit that comes out of that tree."
Imam Ahmad recorded it; its chain contains a narrator, Abdullah bin Abd al-Aziz al-Laythi, whom Imam Malik and Sa'id bin Mansur declared thiqah (trustworthy), while a group called him da'if (weak); the remaining narrators are the narrators of the Sahih.

It is reported about Sayyiduna Abu al-Darda' (may Allah be pleased with him) that a man passed by him while he was planting saplings in Damascus. The man said: "You are doing this, while you are a Companion of the Messenger of Allah?" He said: "Do not be hasty in judging me. I heard the Prophet (peace and blessings be upon him) say: 'Whoever plants a sapling (or tree), then whatever human or whatever creature from among the creatures of Allah eats anything from it, that is counted as charity for that person.'"
Imam Ahmad and al-Tabarani in al-Mu'jam al-Kabir recorded it; its narrators have been declared trustworthy, and there is some criticism of its narrators that does no harm.

A man named Fannaj narrates: I used to work in Dinbadh (a town in Yemen) and look after the land. Sayyiduna Ya'la bin Umayyah (may Allah be pleased with him) came as governor of Yemen, and with him were some men from among the Companions of the Prophet (peace and blessings be upon him). One of those who had come with him came to me while I was in the field watering the crops. He had walnuts in his sleeve. He sat down by a water channel, cracking those walnuts and eating them. Then he gestured to Fannaj and said: "O Persian, come here." He says: I went to him. That man said to Fannaj: "Will you undertake to plant these walnut trees by this water?" Fannaj asked him: "What benefit will that bring me?" The man said: "I heard the Prophet (peace and blessings be upon him) say, with these two ears of mine: 'Whoever plants a tree, then is patient in guarding it and tends it until it bears fruit, then for whatever anyone obtains from its fruit, that person receives the reward of charity in the court of Allah Almighty.'" Fannaj asked him: "Did you hear this yourself from the Prophet (peace and blessings be upon him)?" He said: "Yes!" Fannaj said: "Then I undertake it." The narrator says: That is how the walnuts of Dinbadh began.
Imam Ahmad recorded it; its chain contains a narrator, Fannaj, whom Ibn Abi Hatim mentioned without either declaring him trustworthy or criticising him, and its remaining narrators are thiqat (trustworthy).

Sayyiduna al-Sa'ib bin Suwayd (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: "Whatever any seeker of provision (whether human or animal) takes from the crop of any one of you, Allah Almighty records a reward for that person because of it."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Abdullah bin Musa al-Taymi, who is thiqah (trustworthy) but makes many mistakes; the remaining narrators of this narration are thiqat (trustworthy).

Sayyiduna Abdullah bin Abd al-Rahman al-Ansari (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "(Those that are) firmly rooted in the mud and that give food in times of famine (are the date palms). Whoever sells them, their price is like ashes on a high place which the wind scatters."
Abu Ya'la recorded it; its chain contains a narrator, Fadalah bin Husayn, who is da'if (weak). (Allamah al-Haythami says:) I say: The hadith of Sayyiduna Ali (may Allah be pleased with him) about medicine will come later in the chapter related to medicine.

Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) was asked about date palms, and he said: "They are firmly rooted in the mud, and they are what is eaten in times of famine."
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, al-Mu'alla bin Maymun, who is matruk (abandoned).

Sayyiduna Imam al-Hasan bin Ali (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) said: "Date palms and trees are a blessing for their owners and for their descendants after them, provided they are grateful to Allah Almighty."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Muhammad bin Jami' al-Attar, who is da'if (weak).

Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) instructed his uncle Sayyiduna al-Abbas (may Allah be pleased with him) to order his sons to cultivate qadb, for it removes poverty. (The narrator says:) The word "qadb" means ratbah (green fodder).
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a group of narrators whom I do not know. (Allamah al-Haythami says:) I say: The hadith of Sayyiduna Mu'adh bin Anas (may Allah be pleased with him) will come after this.
