    I am trying to understand how to negate sentences in Arabic and when to use لا, ما, لم and لن. Is this correct:
    لا = used in the present tense
    ما = used in the past tense
    لم = used in the past subjunctive tense
    لن = ???

    laa usually negates the present, but it's use is very widespread.

    maa, I believe in MSA is hardly ever used to denote the negative past. lam is used for this.

    lam, I have already answered this above.

    lan, when added to the imperfect, e.g yaktubu, changes it to "yaktuba"..

    so lan yaktuba = He will not write (so, it is for negating the future)

    This is a very simplified list, but other than 'past subjunctive', it is correct.

    لم takes what is often called the jussive, which differs from the subjunctive in that it is a past indicative form, and requires a sukuun on the 'short' forms (ana, anta, huwa, hiya, naHnu) whereas it drops the nuun on the other forms and is thus identical with the subjunctive.

    As Qureshpor said, لن is followed by subjunctive forms and means 'won't'.

    As an aside, yes, ما negates the past and does occur in MSA, however, it is considered as less formal than لم.

    Here is my corrected summary:
    لا = used to negate the imperfect
    ما = used with the perfect to create a negated past tense that is less formal than that of لم + the jussive
    لم = used with the jussive (e.g., لم يكْتُبْ) to create a negated past tense
    لن = used with the subjunctive (e.g., لن يكْتُبَ) to create a negated future tense

    I consider the jussive to be a mood of the imperfect. So when I say "negate the imperfect" I mean "negate the imperfect in all of its moods, including the the indicative, subjunctive, jussive and imperative moods of the imperfect (it is used indirectly in the imperative mood: when لا is used in the jussive mood, it has the meaning of the negative imperative).
