He added, “Al-Layth held three separate governorships for them on behalf of Ṣāliḥ ibn ʿAlī (1).”

Ṣāliḥ said to ʿAmr ibn al-Ḥārith, “I will not leave al-Layth alone until he agrees to govern for me.”
ʿAmr replied, “He will not do it.”
Ṣāliḥ retorted, “Then I will surely strike off his head!”
So ʿAmr went to al-Layth, warned him, and al-Layth accepted charge of the Bureau of Stipends. He was later appointed governor of al-Jazīrah in the days of Abū Jaʿfar, and head of the central dīwān during the reign of al-Mahdī.

Abū ʿAmr Aḥmad ibn Muḥammad al-Ḥīrī said: “I heard Muḥammad ibn Muʿāwiyah say—while Sulaymān ibn Ḥarb was sitting next to him—‘One day al-Layth ibn Saʿd came out, and people appraised his clothing, his mount, his signet ring, and everything he had on him at between 18,000 and 20,000 dirhams.’
Sulaymān commented, ‘But one day Shuʿbah came out to us, and they valued his donkey, its saddle, and its bridle at between 18 and 20 dirhams.’”

Abū Ṣāliḥ, al-Layth’s scribe, related: “We were standing at Mālik’s door and he refused to narrate hadith. I remarked, ‘What a contrast with our companion!’ Mālik overheard this, admitted us, and asked, ‘Who is your companion?’
I answered, ‘Al-Layth.’
He said, ‘Do you liken us to a man to whom I once wrote about a small quantity of safflower—just enough to dye our children’s clothes—and he sent us the proceeds, the surplus alone amounting to one thousand dinars!’ (2)”

ʿAbd al-Malik ibn Shuʿayb ibn al-Layth reported: “I heard Asad ibn Mūsā say, ‘ʿAbd Allah ibn ʿAlī was hunting down the Umayyads and executing them. He continued: So I entered Egypt in disguise…’”} نن
