ثَبَتٌ

Firmness of heart in war. (Msb, TA.) You say, لَهُ ثَبَتٌ عِنْدَ الحَمْلَةِ He has firmness, or steadiness, on the occasion of the charge, or assault. (S, A.) And لَهُ ثَبَتٌ عِنْدَ الحِمَامِ He has firmness on the occasion of death. (L.) [See also ثَبَاتٌ.]

Hence, (Msb,) A proof, and evidence, or a voucher. (S, Mgh, Msb, TA.) You say, لَا أَحْكُمُ بِكَذَا إِلَّا بِثَبَتٍ I will not decide so unless on the ground of proof, or evidence. (S.) And it is said in a tradition respecting the day of doubt, [i. e. the day of which one doubts whether it be the last of Shaabán or the first of Ramadán,] ثُمَّ جَاءَ الثَّبَتُ أَنَّهُ مِنْ رَمَضَانَ Then came the proof, or evidence, or voucher, that it was of Ramadán. (TA.)

And hence, (Mgh,) applied to a man, (A, Mgh, [in which latter it is said to be tropical when thus applied, but not so in the A,]) and sometimes written ↓ ثَبْتٌ, (TA,) (assumed tropical:) One who is an authoritative evidence, or voucher, by reason of his trustworthiness in that which he relates: (A, TA:) or (tropical:) one who is trustworthy (Mgh, K *) in that which he relates: (Mgh: [in the K, only the plural is mentioned:]) or (assumed tropical:) one who is just, or equitable, [in that which he relates,] and exact, or honest: (Msb:) plural أَثْبَاتٌ. (A, Mgh, Msb, K.)

Also (assumed tropical:) An index, or a table of contents, in which a relater of traditions collects a list of what he has related from others, and of his sheykhs [who are his authorities]: said by some to be a conventional term of the relaters of traditions: perhaps tropical. (TA.)
