<p class='libAr' dir='rtl'>قوله " سكة مأبورة " يقال: هي الطريقة المستقيمة المستوية المصطفة من النخل ويقال: إنما سميت الأزقة سككا لاصطفاف الدور فيها كطرائق النخل، هذا في اللغة. وقد روي عن النبي صلى الله عليه وعلى آله أنه قال: لا تسموا الطريق السكة فإنه لا سكة إلا سكك الجنة. وأما " المأبورة " فهي التي قد لقحت. قال أبو عبيد : لقحت للواحدة خفيفة وللجمع بالتثقيل " لقحت ". يقال: أبرت النخل آبرها أبرا وهي نخلة مأبورة ويقال: " استأبرت غيري " إذا سألته أن يأبر لك نخلك وكذلك الزرع. والآبر: العامل، والمؤتبر: رب الزرع، والمأبور: الزرع والنخل الذي قد لقح. وأما " المهرة المأمورة " فإنها الكثيرة النتاج، وفيها لغتان يقال: قد أمرها الله فهي مأمورة وآمرها - ممدودة - فهي مؤمرة. وقد قرأ بعضهم " أمرنا مترفيها " غير ممدودة يكون هذا من الامر، وروي عن الحسن أنه فسرها فقال: أمرناهم بالطاعة فعصوا. وقد يكون " أمرنا " بمعنى أكثرنا على قوله " مهرة مأمورة " و " فرس مأمورة " ومن قرأها " آمرنا " فمدها فليس معناه إلا أكثرنا و من قرأها مشددة فقال: " أمرنا " فهذا من التسليط ويقال في الكلام: قد أمر القوم يأمرون إذا كثروا وهو من قوله: " مهرة مأمورة ".With regards to his saying «sikka ma’bura», it is said that it is a straight, leveled, path in which there are palm trees aligned. It is said: Paths were only named sikak due to the houses being aligned like the paths of palm trees. This is with regards to the language. It has been narrated of the Prophet, Allah’s blessings be upon him and his Family, that he said: Do not name the path a sikka, for indeed, there is no sikka except for the sikak of Paradise.» As for ma’bura, it is the one that has been fertilized. Abu Ubaida: Luqihat for one is light, and for a plurality it is luqqihat with a heaviness. It is said: «I performed ta’beer to the palm tree, (and) I performed ta’abur to it, in a manner of abr .» It is palm tree that is ma’bura. It is said: «I requested another to perform ta’beer» if I would ask him to pollinate that (particular) palm tree, and so it is with crops. The pollinator is the employed (who pollinates). The seeker of pollination is the owner of the crops. That which is pollinated is the crops and the palm tree that was fertilized. As for the «filly that is ma’mura» it is the one that produces much. There are two lingual meanings to it. It is said: «Allah has done amr to it, and so it has become ma’mura, and if He does ta’amur to it, it is mu’ammara.» Some have recited: «We command its affluent» (17:16) without it being extended [1], and that this is from commandment . It has been narrate of Hasan that he interpreted it and said: «We commanded them to obedience, but they disobeyed». It could be that «We commanded» was in the meaning of «We increased», in accordance to his saying: «a filly that is ma’mura» and «a horse that is ma’mura». Those who recited it as aamarna, by which they extended it, its meaning is nothing but «We increased». There are those who recited is as being intensified, and so they said ammarna, which stems from assigning as authority. It is said in speech: «He has issued an amr to the people. They perform amr if they were to increase» and it is from his saying: «a filly that is ma’mura.»
