Bukhari

(In Surah Ar-Rahman, the word) «صلصال» means such clay in which sand is mixed, and it sounds like baked clay when struck. Some have said that the meaning of «صلصال» is «منتن‏.‏», that is, foul-smelling. Originally, this word is derived from «صل‏». The letter "fa" is repeated, or as the Arabs say from «صرصر», «صر الباب» or «صر صر الباب», when a sound comes from the door upon closing, like «كبكبته» is derived from «كب». In Surah Al-A'raf, the word «فمرت به‏» means "she kept moving about," "completed the period of pregnancy." (In Surah Al-A'raf) the word «أن لا تسجد‏» means «أن تسجد‏.‏», that is, "What prevented you from prostrating to him?" The word «لا» here is extra.

Ibn Abbas (may Allah be pleased with them both) said: In Surah At-Tariq, the word «لما عليها حافظ‏» means «لما» in the sense of «إلا», that is, there is no soul except that there is a guardian appointed over it by Allah. (In Surah Al-Balad) the word «في كبد‏» means hardship, as in «كبد‏». And (in Surah Al-A'raf) the word «ريشا» is the plural of «رياش», meaning wealth. This is the explanation of Ibn Abbas (may Allah be pleased with them both). Others have said that «رياش» and «ريش» have the same meaning, that is, outer garments. And (in Surah Al-Waqi'ah) the word «تمنون‏» means «نطفة», that which you place in the wombs of women (through intercourse). (And in Surah At-Tariq) «إنه على رجعه لقادر‏», Mujahid said its meaning is that Allah can return the semen back into the man (this was connected by Firyabi; most people have interpreted it as meaning that Allah is able to return the man, i.e., resurrect him on the Day of Judgment). (And in Surah As-Sajdah) «كل شىء خلقه» means that Allah has created everything in pairs. The sky is the pair of the earth, man is the pair of woman, the sun is the pair of the moon. And the odd (al-taaq) is Allah Himself, who has no pair. In Surah At-Tin, «في أحسن تقويم‏» means: We created man in the best form and best creation. «أسفل سافلين‏ إلا من آمن» means: Then We reduced man to the lowest of the low (made him among the people of Hell), except for those who believe. (In Surah Al-Asr) «في خسر‏» means misguidance, then the believers are excepted. (He said «الا الذين امنوا»). In Surah As-Saffat, «لازب‏» means clinging (i.e., sticky, adhering). In Surah Al-Waqi'ah, the words «ننشئكم‏‏ في ما لا تعلمون » mean: In whatever form We will, We can fashion you. (In Surah Al-Baqarah) «نسبح بحمدك‏» means: The angels said, "We glorify You." Abu Al-Aliyah said: In the same Surah, «فتلقى آدم من ربه كلمات‏», those words are «ربنا ظلمنا أنفسنا‏». In the same Surah, «فأزلهما‏» means: He made them slip and falter. (In the same Surah) «لم يتسنه‏» means: It did not even become corrupted. From this (in Surah Muhammad) «آسن» means: Corrupted (foul water). From this, in Surah Al-Hijr, the word «مسنون» means: Changed, foul. (In the same Surah) the word «حمإ‏» is the plural of «حمأة», meaning foul mud. (In Surah Al-A'raf) the word «يخصفان‏» means: Both Adam and Hawwa began to join together the leaves of Paradise, placing one over another to cover their private parts. By the word «سوآتهما‏» is meant the private parts. In the word «ومتاع إلى حين‏», «حين‏» refers to the Day of Judgment; the Arabs use «حين‏» for a period ranging from an hour to an endless duration. «قبيله‏» refers to the group of Satan, in which he himself is included.

Narrated Abu Huraira: The Prophet said, "Allah created Adam, making him 60 cubits tall. When He created him, He said to him, "Go and greet that group of angels, and listen to their reply, for it will be your greeting (salutation) and the greeting (salutations of your offspring." So, Adam said (to the angels), As-Salamu Alaikum (i.e. Peace be upon you). The angels said, "As-salamu Alaika wa Rahmatu-l-lahi" (i.e. Peace and Allah's Mercy be upon you). Thus the angels added to Adam's salutation the expression, 'Wa Rahmatu-l-lahi,' Any person who will enter Paradise will resemble Adam (in appearance and figure). People have been decreasing in stature since Adam's creation.
