Yousay also, رَكَضَ الرَّجُلُ (tropical:)  The man struck the ground with his foot: and رَكَضَتِ الخَيْلُ (tropical:)  The horses struck the ground with their hoofs: and جَآءَتِ الخَيْلُ رَكْضًا (tropical:)  [The horses came striking the ground with their hoofs]: and رَكَضَتِ الجُنْدَبُ الرَّمْضَآءَ بِكُرَاعَيْهَا (tropical:)  [The locusts termed جندب struck the vehemently-hot ground with their two legs]: and تَرَكْتُهُ يَرْكُضُ بِرِجْلِهِ لِلْمَوْتِ (tropical:)  [I left him striking the ground with his foot previously to death: see also 8]. (A.) [The above-mentioned phrases  marked as tropical are so marked on the authority of the A: but the reason of their being so I do not see.] b2:  They also said, sometimes, رَكَضَ الطَّائِرُ, meaning (assumed tropical:)  The bird moved his wings in flying: (S:) the inf. n., رَكْضٌ, signifying (tropical:)  the act of moving the wing: (K, TA:) and الطَّائرُ يَرْكُضُ بِجَنَاحَيْهِ (tropical:)  The bird moves his wings, and puts them back against his body: (A, TA:) or the former of these two phrases means (assumed tropical:)  the bird was quick, or swift, in his flying.

(Har p. 660.) b6:  See also 4.رَكْضَةً An impulse: a motion: (K:) [pl. رَكَضَاتٌ: see an ex. voce رَفَضَاتٌ.] Hence, (TA,) it is said in a trad. of I'Ab, that the blood which continues to flow after menstruation is رَكْضَةٌ مِنَ الشَّيْطَانِ, (S, * TA,) i. e.
