The virtue of performing Hajj on foot

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that he fell seriously ill, so he called his children, gathered them, and said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever performs Hajj on foot from Makkah until he returns to Makkah, Allah Almighty records for him seven hundred good deeds for every step, and each good deed is equal to the good deeds of the Haram." It was asked: What are the good deeds of the Haram? He said: "One hundred thousand good deeds for each good deed."
The chain of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that one day before the Day of Tarwiyah (the 8th of Dhu al-Hijjah), the Messenger of Allah (peace and blessings be upon him) would deliver a sermon to the people and inform them about their rites of Hajj.

It is narrated from Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) that it is the Sunnah of Hajj that the imam should offer the Zuhr, Asr, Maghrib, Isha and Fajr prayers at Mina, then set out for Arafah and take his midday rest wherever it is possible for him, until, when the sun passes its zenith, he should address the people, then offer the Zuhr and Asr prayers together, combining them; then he should stand at Arafat until the sun sets, then depart from there and pray at Muzdalifah or wherever Allah decrees, then stay at Muzdalifah until, when dawn breaks and it becomes quite light, he should move on before sunrise. Then, when he has stoned the Great Jamrah, everything that was forbidden to him (because of ihram) becomes lawful for him, except women and perfume, until he visits the House of Allah (tawaf al-ifadah).
