Rukhshah (relief) in the Sunnah Prayers

Abdullah ibn Umar radhiallahu anhuma he said: كان رسول الله صلى الله عليه وسلم يسبح على الراحلة قبل أي وجه توجه ويوتر عليها غير أنه لا يصلي عليها المكتوبة "Prophet sallallaahu 'alaihi wasallam prayed sunnah above mount, facing any direction steed facing. And he prayed Witr on it, but he never did the obligatory prayers on the mount. "(Narrated by Al-Bukhari no. 1098) from Amir ibn Rabiah radhiallahu anhu he said: رأيت رسول الله صلى الله عليه وسلم وهو على الراحلة يسبح يومئ برأسه قبل أي وجه توجه ولم يكن رسول الله صلى الله عليه وسلم يصنع ذلك في الصلاة المكتوبة "I saw the Prophet sallallaahu 'alaihi wasallam above animal horse praying sunnah by gesturing with his head towards any animal horse face. Prophet sallallaahu 'alaihi wasallam never been done like this for the obligatory prayer. " (Narrated by Al-Bukhari no. 1097 and Muslim no. 701) From Abdullah bin Al Uqaili Syaqiq he said: I once asked Aisha about the prayer (sunnah) of his Prophet sallallaahu 'alaihi wasallam. So Aisha radhiallahu anha replied: كان يصلي ليلا طويلا قائما وليلا طويلا قاعدا وكان إذا قرأ قائما ركع قائما وإذا قرأ قاعدا ركع قاعدا "He used to pray the night so long as he stood, and he also used to perform the night prayers while sitting for so long. If she read while standing, then he bowing to the stand, and when he read while sitting, then he bowing while sitting. "(Narrated by Muslim no. 730) From Abdullah ibn Amr radhiallahu anhuma he said: حدثت أن رسول الله صلى الله عليه وسلم قال: صلاة الرجل قاعدا نصف الصلاة. قال: فأتيته فوجدته يصلي جالسا فوضعت يدي على رأسه. فقال: ما لك يا عبد الله بن عمرو? قلت: حدثت يا رسول الله أنك قلت: صلاة الرجل قاعدا على نصف الصلاة, وأنت تصلي قاعدا? قال: أجل ولكني لست كأحد منكم "Told me that the Prophet sallallaahu 'alaihi wasallam said:" Prayer is done by someone who sits obtain half the reward of prayer (with stand). 'Abdullah bin' Amr said: Then I see him, it turns out I found him praying at seat. Then I put my hand on his head, then he said, "What's with O 'Abdullah bin' Amr?" I replied, "Presented to me, O Messenger of Allah, that you said, "Prayer person sitting gets half the reward of prayer with stand," then why do you pray to the seat? "He replied," Yes, but I do not like you. "(Narrated by Muslim no. 735) means: Reward stay perfect despite my prayers I pray while sitting, unlike you.



A brief explanation:
Allah Ta'ala the prayers prescribed sunnah as a complement to the obligatory prayer, and He laid down some laws that are different with respect to the laws that apply in the obligatory prayers. That was to facilitate the servants of the sunnah prayers and that they motivated to reproduce the prayers this sunnah.

Among the laws that apply specifically to the prayers Sunnah are:
a. Bolehnya sunnah prayers on the vehicle. Therefore, it can not obligatory prayer on the vehicle except for existing elderly.
b. In the vehicle, he was not required to face Mecca, but he was facing any direction the vehicle is facing.
c. Can pray sitting under a mutak, whether or not the vehicle is in the vehicle, whether sick or not. It's just that when she sat in a state of prayer is no prayer udzur only half the reward of praying standing. But when he prayed sitting because there is an excuse then insha Allah reward perfect prayer.
d. In prayer sitting, for bowing and prostration replaced with a signal head, which he bowed his head slightly instead of bowing and subdue it lower instead of prostration. Hence the move / gesture down here is the head, the body does not come down.
e. If he reads (al-Fatihah and letters) sitting under the disunnahkan ruku'nya also hinted sit under his head.
