سهد (root shd)

Al-sahd and al-sihād (السهد والسهاد) are two dialectal forms… the opposite of ruqād (sleep). "I saw no sahda (سهدة) from so-and-so" means a matter I could rely on, whether blessing, good, or hope-inspiring speech. Sahdad (سهدد) is the name of a mountain, and it is not declined (diptote).

Al-sihād (السهاد) is wakefulness. The man sahida (سهد), with kasra, yashadu, sahdan. Al-suhd (السهد), with ḍamma on the sīn and hāʾ, is a small amount of sleep. Abū Kabīr al-Hudhalī said: "She brought him forth, wild-hearted, lean-bellied, / sleepless when the dull-witted man sleeps at night." I sahhadtuhu (سهدته), so he is musahhad. "I saw no sahda (سهدة) from so-and-so" means a matter I could rely on, whether speech or news.

Sīn, hāʾ and dāl (سهد) are two divergent words. One indicates the opposite of sleep; the other indicates stillness. The first is sihād (السهاد), which is little sleep. A man is sahid (سهد) if he sleeps little. He said: "She brought him forth, wild-hearted, lean-bellied, / sleepless when the dull-witted man sleeps at night." I sahhadtu (سهدت) so-and-so when I drove sleep from him… The other word is their saying shayʾ sahd mahd (شيء سهد مهد), meaning still, not troublesome. It is also said, "I saw no sahda (سهدة) from so-and-so", meaning a matter I could rely on, whether news or speech, or one I could find repose in.

Al-Layth: al-sahd and al-sihād (السهد والسهاد) are the opposite of ruqād (sleep). Al-Aʿshā said: "I stayed awake, and what is this sleeplessness that keeps one awake?" Al-Jawharī: al-sihād is wakefulness, and al-suhd (السهد), with ḍamma on the sīn and hāʾ, is a small amount of sleep. He sahida (سهد), with kasra, yashadu, sahdan, suhdan and sihādan: he did not sleep. A sahid (سهد) man is one who sleeps little. Abū Kabīr al-Hudhalī said: "She brought him forth, wild-hearted, lean-bellied, / sleepless when the dull-witted man sleeps at night." An eye is likewise sahid. Anxiety and pain have kept him from sleep. "I saw no sahda (سهدة) from so-and-so" means a matter I could rely on, whether good, blessing, news, or persuasive speech. "So-and-so is dhū sahda" means he is alert. "He is more wakeful (asahd) in judgment than you." In the chapter on paired echo-words: shayʾ sahd mahd means something good. Al-suhūd (السهود) means tall and strong. Shamir said: a boy is suhūd if he is tender and young. He recited: "Would that he were a suhūd boy, / when his branches grow dense they renew themselves." I sahhadtuhu (سهدته), so he is musahhad. "So-and-so yushad" means he is not allowed to sleep. To this belongs the saying of al-Nābigha: "The one bitten by it is kept awake from the evening sleep, / with women's ornaments rattling in his hands." Ibn al-Aʿrābī: when a woman gives birth to her child in a single push, it is said of her: amṣaʿat bihi, akhfadat bihi, asʾhadat bihi, amhadat bihi, and ḥaṭaʾat bihi. Sahdad (سهدد) is the name of a mountain and is not declined, as if they were treating it as a rock or a patch of ground.
