ريث

رَيْثٌ ذ A space, or measure, [ of time, ] syn. قَدْرٌ, (T, Msb,) or مِقْدَارٌ; (A, K;) or a time, a while, syn. سَاعَةٌ. (Mgh.) You say, أَمْهَلْتُهُ رَيْثَمَا فَعَلَ كَذَا, i. e. قَدْرَ مَا فَعَلَهُ (Msb) or سَاعَةَ فِعْلِهِ (Mgh) [ I granted him a delay during the space of his doing such a thing ]. And لَمْ يَلْبَثْ اـِلَّا رَيْثَمَا قُلْتُ, i. e. قَدْرَ ذٰلِكَ [ He tarried not save during the space that, or as long as, or while, I said such a thing]. (TA, from a trad.) And so in the saying, مَا قَعَدَ عِنْدَنَا فُلَانٌ اـِلَّا رَيْثَ أَنْ حَدَّثَنَا بِحَدِيثٍ تُمَّ مَرَّ [ Such a one sat not with us, or at our abode, save during the space that, or as long as, or while, he related to us a story, or tradition; then he went away ]. (T, TA.) And it is used without ما and without ان: (TA:) Aashà Báhileh says, لَا يُصْعِبُ الأَمْرَ اـِلَّا رَيْثَ يَرْكَبُهُ وَ كُلَّ أَمْرٍ سِوَى الفَحْشَاآءِ يَأْتَمِرُ [ He finds not the affair difficult save while he is embarking in it; and every command but that which exceeds the bounds of rectitude he obeys ]: (M, TA:) this mode of expression is common in the dial. of El-Hijáz; accord. to which one says, يُرِيدُ يَفْعَلُ, i. e. أَنْ يَفْعَلَ. (TA.) [See also an ex. in a verse cited voce رَاجِلَةٌ, and another in a verse cited voce رِيحٌ.]
