Its chain of transmission is sound.

He likewise narrated—with an equally sound chain—from Dāwūd, who related that ʿAbd Allāh ibn Salām said to him: “If you hear that the Dajjāl has emerged while you are planting a wadiyyah (a young date-palm shoot), do not rush off before finishing its cultivation, for people will still go on living after that.”

This Dāwūd is Ibn Abī Dāwūd al-Anṣārī; al-Ḥāfiẓ said about him, “maqbūl” (acceptable).

Ibn Jarīr also narrated from ʿUmārah ibn Khuzaymah ibn Thābit, who said: “I heard ʿUmar ibn al-Khaṭṭāb say to my father, ‘What is keeping you from planting your land?’ My father replied, ‘I am an old man who may die tomorrow.’ ʿUmar said, ‘I insist that you must plant it!’ I actually saw ʿUmar ibn al-Khaṭṭāb planting it with his own hand together with my father.”

So it appears in al-Suyūṭī’s al-Jāmiʿ al-Kabīr (3/337/2).

For this reason some of the Companions regarded a man who works to improve his land as one of Allah’s workers. Al-Bukhārī narrated in al-Adab al-Mufrad (no. 448) from Nāfiʿ ibn ʿĀṣim that he heard ʿAbd Allāh ibn ʿAmr say to a nephew of his who had come from al-Wahṭ: “Are your laborers working?” He replied, “I do not know.” ʿAbd Allāh said, “Had you been a Thaqafī you would have known what your workers are doing.” Then he turned to us and said, “When a man works alongside his laborers in his own household”—and the narrator once said, “in his property”—“he is a worker among the workers of Allah.” Its chain is ḥasan, Allah willing.

Al-Wahṭ in the language means “orchard”; it was an extensive piece of land that belonged to ʿAmr ibn al-ʿĀṣ in Ṭāʾif, three miles from Wajj, and it appears that he left it to his children,
